Part VI. Keyboard Shortcuts

The following table summarizes the keyboard shortcuts built into ImageJ. You can create additional shortcuts, or override built-in ones, by creating simple macros and adding them to the StartupMacros.txt. You can also assign a function key to a menu command using PluginsShortcutsCreate Shortcuts…↑.
Several of these shortcuts accept key modifiers as described in Key Modifiers↓. Also note that, except when using the Text Tool↑, you do not need to hold down the control key to use a keyboard shortcut, unless Require control key for shortcuts in EditOptionsMisc…↑ is checked.
