GIMP/工具箱

GIMP提供了一个综合的工具箱，以便于快速执行基本任务。工具箱可充分定制，这意味着您可以添加或移除任何工具。您只要到窗口 > 可停靠对话框 > 工具选择要添加或移除的工具即可。

默认情况下，并不是所有的工具都会被显示出来，比如GEGL操作和颜色工具就被省略了。通过工具菜单，你可以打开所有工具。想切换到工具箱窗口，你可以使用Ctrl+B组合键。当然了，这里说的都是默认情况下的快捷键，你可以通过编辑 > 快捷键进行调节。

By default, activating any tool, will have the effect of showing its options under the toolbox. Each tool has its own set of settings and any changes to them are kept through the current session. There are also four buttons under any options.

Save options to... - save options of the current tool
Restore options from... - restore options from saved file
Delete saved options... - delete saved options
Reset to default values - reset the settings to default values.

You can hide them by clicking on the arrow next to the tool name and deselecting Show Button Bar. You can also access these from the same menu under Tool Options Menu.
