||||||||
Objective [Heading] | rr_ObjectiveHeading | Investment Objective | ||||||||

Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the BlackRock-advised fund complex. More information about these and other discounts is available from your financial professional and in the “Details about the Share Classes” section on page 20 of the Fund’s prospectus and in the “Purchase of Shares” section on page II-71 of the Fund’s statement of additional information. | ||||||||

Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover: | ||||||||
Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was approximately 60% of the average value of its portfolio. | ||||||||
Portfolio Turnover, Rate | rr_PortfolioTurnoverRate | 60.00% | ||||||||
Expenses Deferred Charges [Text Block] | rr_ExpensesDeferredChargesTextBlock | A contingent deferred sales charge (“CDSC”) of 0.75% is assessed on certain redemptions of Investor A Shares made within 18 months after purchase where no initial sales charge was paid at time of purchase as part of an investment of $500,000 or more. | ||||||||

Expense Example [Heading] | rr_ExpenseExampleHeading | Example: | ||||||||
Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||
Expense Example, No Redemption, By Year, Caption [Text] | rr_ExpenseExampleNoRedemptionByYearCaption | You would pay the following expenses if you did not redeem your shares: | ||||||||
Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies of the Fund | ||||||||
Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund normally invests at least 80% of its assets in floating rate investments and investments that are the economic equivalent of floating rate investments, which effectively enables the Fund to achieve a floating rate of income. These investments may include, but are not limited to, any combination of the following securities: (i) senior secured floating rate loans or debt; (ii) second lien or other subordinated or unsecured floating rate loans or debt; and (iii) fixed-rate loans or debt with respect to which the Fund has entered into derivative instruments to effectively convert the fixed-rate interest payments into floating rate interest payments. The Fund may also purchase, without limitation, participations or assignments in senior floating rate loans or second lien floating rate loans. For purposes of the Fund’s investments, the term debt includes investments in convertible or preferred securities. The Fund may invest in investments of any credit quality without limitation, including investments rated below investment grade. The Fund anticipates that, under current market conditions, a substantial portion of its portfolio will consist of leveraged loans rated below investment grade and similar investments. These investments are expected to exhibit credit risks similar to high yield securities, which are commonly referred to as “junk bonds.” The Fund may invest up to 20% of its assets in fixed income securities with respect to which the Fund has not entered into derivative instruments to effectively convert the fixed-rate interest payments into floating-rate interest payments. Such fixed income securities include, but are not limited to, corporate bonds, preferred securities, convertible securities, mezzanine investments, collateralized loan obligations, senior loans, second lien loans, structured products and U.S. government debt securities. The Fund’s investments in any floating rate and fixed income securities may be of any duration or maturity. The Fund may invest in securities of foreign issuers, including issuers located in emerging markets, without limitation. The Fund may also invest up to 15% of its assets in illiquid securities. The Fund may also invest in companies whose financial condition is uncertain, where the borrower has defaulted in the payment of interest or principal or in the performance of its covenants or agreements, or that may be involved in bankruptcy proceedings, reorganizations or financial restructurings. The Fund may invest up to 10% of its assets in common stocks or other equity securities. In addition, the Fund may acquire and hold such securities (or rights to acquire such securities) in unit offerings with fixed income securities, in connection with an amendment, waiver, conversion or exchange of fixed income securities, in connection with the bankruptcy or workout of a distressed fixed income security, or upon the exercise of a right or warrant obtained on account of a fixed income security. The Fund may buy or sell options or futures on a security or an index of securities, buy or sell options on futures or enter into credit default swaps and interest rate or foreign currency transactions, including swaps and forward contracts (collectively, commonly known as derivatives). The Fund may use derivatives for hedging purposes, but is not required to, as well as to increase the total return on its portfolio investments. |

Risk [Heading] | rr_RiskHeading | Principal Risks of Investing in the Fund | ||||||||
Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks of investing in the Fund.

Bar Chart and Performance Table [Heading] | rr_BarChartAndPerformanceTableHeading | Performance Information | ||||||||
Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The information shows you how the Fund’s performance has varied year by year and provides some indication of the risks of investing in the Fund. The table compares the Fund’s performance to that of the S&P Leveraged Loan Index. The Fund acquired the assets and liabilities of BlackRock Senior Floating Rate Fund, Inc. (“Predecessor Fund”) in a reorganization on March 21, 2011. The Predecessor Fund’s performance and financial history have been adopted by the Fund and will be used going forward from the date of the reorganization. As a result, the total returns for Investor A Shares in the chart below prior to the date of the reorganization are those of the Predecessor Fund’s shares of Common Stock. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. The returns in the table for Investor A, Investor C and Institutional Shares are based on the Predecessor Fund’s shares of Common Stock adjusted to reflect the applicable sales charges, if any. The returns for Investor A, Investor C and Institutional Shares are also adjusted to reflect the applicable expenses and distribution and service (12b-1) fees, if any. As with all such investments, past performance (before and after taxes) is not an indication of future results. If the Fund’s investment manager and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund’s returns would have been lower. Updated information on the Fund’s performance can be obtained by visiting http://www.blackrock.com/funds or can be obtained by phone at 800-882-0052. | ||||||||
