Keyboard Shortcuts

There are many keyboard shortcuts for general actions--such as menu item actions--and many shortcuts specifically for editing assembly language programs in text windows. Here is a list of those shortcuts.

Notes:

• The Command key is used instead of the Control key on Macintosh computers.
• The Keyboard Shortcuts shown below are the default shortcuts. Nearly all of these can be changed by the user. To change the shortcuts, simply navigate to the "Key Bindings" tab of the Preferences dialog. Click on the keyboard shortcut you wish to change and type in a new shortcut. You needn't press the Ctrl/Cmd key, which is automatically added.
