Indication of modifier buttons to tools and dialogs
I just wanted to highlight an emerging problem to catch it in its cradle.
The new tool and dialog patches that has been merged are great. But they
also introduce secret functionaly, examples:
Ctrl + click: highlights net ( modifier to select tool )
ctrl + drag: snap angles in arc tool
shift + click: adds/removes to selection in select mode
shift + scroll: changes increment values in 3d-previewer
These are the few examples I found right now, what I would like to see
is a standardized way of informing the users to this before more tools
get these hidden functionality.
The way that current shortcuts are indicated I think are great ( the
grey text next to their selection in menus Maybe we could expand on this
to create tooltips to the menus with a list of modifier keys for the
hovered tool in the menu.
Another way that Gimp uses is to put this information at the bottom
information bar, Maybe we could do that as well by modifying the current
position information bar
Yet another way would be to have tool specific settings given screen
real-estate, much in the way of gimp and inkscape.
At least I think this issue should be addressed and agreed upon before
tools specify their different modifiers willy-nilly all over the place
and you need a kicad-phd to remember them all. Just having an idea on
how to do it can enable a good team-effort of supporting it.
