What I was doing earlier is -- if a valid keystroke was found, it was added to the current sequence and then the key was disposed, so the letter does not appear at the cursor.
What I changed it to -- I decreased the time out from 1.5 sec to 1 sec. And I removed the disposal of the key after adding it to the sequence. So now, you can continue typing, without being bothered if a combo was triggered.
The only problem now is, if you type (for example) "SUPPOSE", you can obviously do that within 1 sec, and then the toolbar will recognize the combo SUP which will immediately search G4EF for today's posts and will display it on your current tab.
I hope I can solve that too.
