Expandinfg folders in tree using keyboard

[poldem]

I would like to expand a folder in the tree area.

I can do it by mouse clicking on + sign. Of course this works !
I have tried to do it also using the numeric keypad <+>, but it does not work.

I am a new user here, used to windowsExplorer and used to do it this way (old habits die hard...)

The same applies to contracting folders with - key.

I have tried to find a setting for this in options, but no success
Is this possible in FreeCommander ?

Try left and right arrows.

Try left and right arrows.

Cool.
And it is also the only logical answer - up and down is obvious, left and right are now obvious too.

Thanks
