Is it possible in Bricscad to replicate the selection lock toggle that is was the spacebar in 3dsmax? So very useful.
Ideally it would preserve the locked selection set for multiple commands.
More basically what I want is to avoid the following frequent frustration: after no little effort of selecting entities, faces, edges, vertices, whatever, I go to start a command by quad or keyboard, but in the process my cursor inadvertently hovers over a nearby face, which gets highlighted automatically and—even without my clicking on it—becomes incorporated into the command I've just started. So then I have to cancel the command, if I notice immediately, or undo, if I notice later. Either way I end up having to start the whole selection process all over again... and hope more uninvited guests don't show up.
