it seems illustrator adds and subtracts to selection with the same command: `shift` + click. I want to change this so that adding command is `shift` + click while subtracting is `ctrl` + click.

This would make things so much easier, for example: I have many straight lines from end to end of the artwork. Some lines though, are shorter. I want to select all the short lines, which vary in length, but are still shorter than the bigger ones.

Currently, I select all lines and then I have to `shift` + click every long line to deselect it.

If the commands could change, I could select all lines, then `ctrl` + click and create a selection window barely touching the longest lines, deselecting them.

This would be coherent with many software out there such as Autocad, Rhino, etc.

Thanks
