[Lazarus] Lazarus shortcuts conflict with windows shortcuts

[Jürgen Hestermann]

I saw that quite a lot of keyboard shortcuts in Lazarus use Ctrl+Alt combos.
On Windows this is not a good idea because (system wide) user shortcuts
for programs on the desktop use Ctrl+Alt combos too so they conflict with each other.
Is it realy necessary to use Ctrl+Alt combos?
I think there should be enough Ctrl+Shift and Alt+Shift combos available for all functions.
But maybe it's already too late to change this.
