[Lazarus] Alt key to set column selection mode is broken

[Graeme Geldenhuys]

Hi,

I have a suggestion to the Alt key for column section. Currently it
doesn't work at all on Linux and probably *BSD too. The problem is two fold.

1) This is because the Alt+Click+Drag is already used by X11 to move
   windows around (without doing in from the title bar).

2) Even though the description of that feature says Alt key, Lazarus
   actually means "Left Alt" key only.

What if Lazarus changes that option to use the Right Alt key instead.
Currently this is not used by X11, and seeing that Lazarus seem to
differentiate between Left Alt and Right Alt anyway, this could be a
solution that could work on all platforms?
