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 156% of the average value of its portfolio. | ||||||||||||||||||||||
Portfolio Turnover, Rate | rr_PortfolioTurnoverRate | 156.00% | ||||||||||||||||||||||

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: | ||||||||||||||||||||||

Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies of the Fund | ||||||||||||||||||||||
Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal circumstances, Flexible Equity Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities and equity-like securities and instruments with similar economic characteristics. The Fund seeks to invest primarily in securities issued by North American companies. The Fund may invest in companies of any capitalization size, style or sector. Equity securities consist primarily of common stock, preferred stock, securities convertible into common stock and securities or other instruments whose price is linked to the value of common stock. The Fund may also invest in equity securities of foreign issuers, including securities of companies in emerging market countries. The Fund may invest directly in foreign securities or indirectly through depositary receipts and similar instruments. The Fund may invest in derivatives, including but not limited to, total return and credit default swaps, options, futures, options on futures and swaps, and foreign exchange transactions, for hedging purposes, as well as to enhance the return on its portfolio investments. The Fund may invest up to 20% of its net assets (plus any borrowings for investment purposes) in fixed income securities when, in the view of the portfolio manager, these securities offer better risk-adjusted return potential than equity securities. The Fund may invest in fixed income securities of any rating, which may include high yield securities (commonly called “junk bonds”), and the Fund may invest up to 10% of its net assets in distressed securities that are in default or the issuers of which are in bankruptcy. The Fund may seek to provide exposure (up to 20% of the Fund’s total assets) to the investment returns of real assets that trade in the commodity markets through investment in commodity-linked derivative instruments and investment vehicles that exclusively invest in commodities such as exchange traded funds, which are designed to provide exposure to commodity markets without direct investment in physical commodities. The Fund may gain such exposure to commodity markets by investing up to 20% of its total assets in BlackRock Flexible Equity Fund Subsidiary, Ltd. (the “Subsidiary”), a wholly owned subsidiary of the Fund formed in the Cayman Islands, which invests primarily in commodity-related instruments. In order to seek to mitigate risk or lower overall volatility, the Fund may invest up to 20% of its net assets in cash or cash equivalents. |

Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | Risk is inherent in all investing. The value of your investment in Flexible Equity 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 | Effective July 31, 2012, Flexible Equity Fund changed its investment objective and its investment strategies. Performance for the periods prior to July 31, 2012 shown below is based on the investment strategies utilized by the Fund prior to July 31, 2012, which focused on investing in equity securities issued by U.S. mid-capitalization value companies. On January 31, 2005, the Fund reorganized with the State Street Research Mid-Cap Value Fund (the “SSR Fund”), which had an investment objective and strategies similar to those of the Fund prior to July 31, 2012. For periods prior to January 31, 2005, the chart and table show performance information for the SSR Fund. The returns for Class R Shares prior to July 30, 2010 (the date Class R Shares commenced operations) are based on the Fund’s Investor A Shares adjusted to reflect the class specific fees applicable to Class R Shares. 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 as it was managed pursuant to its investment objective and investment strategies prior to July 31, 2012. Effective July 31, 2012, the Fund changed its benchmark index from the Russell Midcap® Value Index to the Standard & Poor’s 500® Index (“S&P 500 Index”) in conjunction with the Fund’s new investment strategy and its exposure to a broader range of equity securities. The table compares the Fund’s performance to that of the S&P 500 Index and the Russell Midcap® Value Index. As with all such investments, past performance (before and after taxes) is not an indication of future results. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. If BlackRock 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 results can be obtained by visiting http://www.blackrock.com/funds or can be obtained by phone at (800) 882-0052. |
