Version: (using KDE 4.2.90) Installed from: SuSE RPMs Currently user can easily deselect using keyboard, but not mouse. However it would be useful and consistent. Please note, that single LMB click is zero selection area, this means: any area A \ single LMB => A any area A + single LMB => A any area A -> single LMB should be => empty erea but it is => A PS. LMB click outside the area A.
Our selection tools do need usability updates -- but we need to make a real design first.
I would like to add that a single click selection is so hard to see it could be confusing for users who expect to perform deselect with a single click and then have no other tools function.
