GIMP/工具箱

GIMP提供了一個綜合的工具箱，以便於快速執行基本任務。工具箱可充分客製化，這意味着您可以添加或移除任何工具。您只要到窗口 > 可停靠對話方塊 > 工具選擇要添加或移除的工具即可。

預設情況下，並不是所有的工具都會被顯示出來，比如GEGL操作和顏色工具就被省略了。通過工具選單，你可以打開所有工具。想切換到工具箱窗口，你可以使用Ctrl+B組合鍵。當然了，這裏說的都是預設情況下的快速鍵，你可以通過編輯 > 快速鍵進行調節。

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.
