Do you know that you can customize ALL shortcut key settings in DESIGNrev/MDPview/WORKbench?
We have default shortcut key binding for frequently used menu items. If you have a better set of key binding that you are used to, you can try to set your own by changing the keyprefs file under ~/.calibrewb_workspace directory. The key bindings can be defined in the keyprefs file using the following command
bindKey <keyname> [ cwbFunction | user_proc ] [[null] menu_name "menu_pick"]
If you don't know how to do that, you can even find an example under .calibrewb_workspace/keyprefs.template
Hope this will help you improve your productivity.
