i want to invert hotkey "Go back" (alt+left arrow) and "go tabselect -1" (ctrl+left arrow), and "Go foward" (alt+right arrow) and "go tabselect +1" (alt+right arrow).
But there are problem with "go back" and "go foward".
if i try with alt+Left arrow and alt+Right arrow, there are no problem but with ctrl+Left arrow and ctrl+Right arrow, dual mode open !!!!
Try turning all of your toolbars ON before you look at the Keys page in Customize... THEN make sure you don't see any red conflicts for th CTRL+right/left arrow. Not sure why you wouldn't see the same problem with the tabselect command and this key combo, but maybe you do in fact have some conflict that you're just not seeing yet, and when you don't have a toolbar switched on and some of it's buttons have hotkey assignments, you do not see their key mappins on the Keys page...
I've been kind of following this thread however I really cannot offer anything either. It seems obvious to me that you have a hotkey conflict somewhere AlbatorIV although I can't see one in your screen shots. I do not read French though, so I may be missing something.
Like steje and Nudel I can set my machine up the way you want to do yours, and mine works fine.
In your first post in this thread you mentioned something about the lister going to dual mode when you use the CTRL+arrow keys. If you can find the reason why that happens (a long forgotten button you once made? A custom menu command perhaps?) you may find your answer.
Well, if he exports his settings maybe we can find something in his Prefs.dpf or something somewhere else???
AlbatorIV... if you export all settings, you can then rename the .dps file to .zip and extract it. Inside, there will be a Prefs.dpf file (it's just ascii data) that you can perhaps search and locate the rouge key binding...
