Hi
I would like to reach every component that takes user input on an SWT
GUI (RCP application) using hotkeys/accelerator keys. So far, I managed
to implement this using Button, Label and Group objects ("&" in the text
property). However, I'd like to reach Text, Combo an Table objects
aswell using keys different than "tabbing" the cursor through the whole
tab order until the cursor is on the desired component.
Can this be done in an easy way?
.... or do I have to implement listeners that control the focus?
If the listener-solution is the way to go, how would you design focus
control of an entire GUI so that EVERY UI component is accessed using
the same mechanisms?
Thanks for your help in advance!

You can also define an accelerator for a Menu:
