Proposal is very simple.
Because the help tab in IDE is a special and unique one, I suppose, it would be convenient to have a key for switching between current code tab and help tab. Something like pressing F1 within help tab switches back to code or some new key.
In the other hand pressing F1 while withing code tab (when Help tab is already opened) doesn`t reset Help back to the root article, but simply switches from current code tab to Help tab.
It is trivial but saves much time of frequent mouseclicking while learning U++ with IDE Help.
Not sure I quite understand what you suggest.
Current behaviour: F1 in code editor switches to Help (article not changed). F1 in help closes items in the tree. Ctrl+Tab in Help goes back to code.
Do you suggest to F1 in help to behave as Ctrl+Tab instead of closing the tree? (A good idea IMO). Or even something else?
