Hello. I can assign keyboard shortcuts, but they never work. I'm using PL 14.10 on Mac OS 10.5.1.
To reproduce the problem:
1. Go to Preferences > Usage > Keyboard Layout > Common Tools.
2. Assign any unused key combination to a tool. For example, assign Control-T to the Text Tool. Click Assign. Note that the shortcut is recorded under "Shortcuts." Click OK.
3. Open a document. Press Control-T (or Command-T -- see below) while the Text Tool is not active. The Text Tool is not activated.
I have tried this process with every combination of modifier keys without success. One oddity is that whether you enter Command or Control as part of a shortcut, the modifier is always recorded as "Command." But even shortcuts that don't use Command or Control don't work for me.
