Revit 2011 supports user defined keyboard shortcut for both build-in commands and API addin commands. Here we show you the way to set your own keyboard shortcut for your addin commands. Before the setting, please make sure “Add-ins” tab shows up in your Revit ribbon and your addin commands shows up under the “Add-ins” tab.

Go to “View” tab, click the “User Interface” dropdown menu, and select the “Keyboard Shortcuts” item like following pic.

Then in the pop up dialog, select “Add-ins tab” in the Filter dropdown combobox, like following pic:

After the selection, you can see all your commands under Add-ins tab, choose the command item and input the keyboard shortcuts in the “Press new keys” area, then click “Assign” button:

Click “OK” to close the Keyboard Shortcuts dialog. Then you can use your new defined shortcuts for your own commands now.
