Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: Arch Linux, no DE, i3wm
Graphics card: GTX 960
Blender Version
Broken: 2.80
Worked: 2.79
Short description of error
I'm left-handed on the tablet, so I bind my sculpt hotkeys to the numberpad. Binding NumpadEnter+LMB to sculpt inverted (same as holding Ctrl) no longer works in 2.80. However, binding NumpadEnter+MMB to pan the view does work. Not sure where the conflict is. This setup did work in Blender 2.79.
Exact steps for others to reproduce the error
Load factory settings
Import .py keymap provided (or bind manually; sculpt.brush_stroke and view3d.move)
Enter sculpt mode
Attempt to sculpt inverted by holding NumpadEnter+LMB

I also have issues with custom modifier keys. Namely "spacebar". For instance if I have a hotkey assigned to "spacebar R". This doesn't work unless I have deactivated any hotkey that is using "R". The software doesn't register that "spacebar" is putting existing keys into a different modified state.

Another weird quirk is that "shift Right Mouse (view3d.cursor3d)" cannot be reassigned to any other hotkey and maintain its drag function. For instance if I assign view3d.cursor3d to "alt right mouse" I am unable to use the drag cursor functionality. Somewhat strangely, if you disable "shift right mouse for view3d.cursor3d" the hotkey still works no matter what. It's like the blender thinks this hotkey is so essential that there is no way to dispose of it or change it to something else.
I would love if the hotkey editor were completely transparent and didn't hide functionality from the user as I keep running into conflicts where blender acts like it can be completely customizable, but behind the scenes it's holding back.

That's strange, but it seems that is designed to work like this. See:
https://developer.blender.org/diffusion/B/browse/master/source/blender/windowmanager/intern/wm_event_system.c$2050-2052
keymodifiers other than
Ctrl, Shift, Alt, OSkey
are not checked by keymaps without keymodifiers.This causes the first keymap in the list (which in this case is the one with
Left Mouse
and without theNumpad Enter
modifier) to be used.A workaround is to move the keymap without the modifier to the bottom of the list (by deleting the keymap that has only
Left Mouse
and creating it again).Added subscriber: @peroro
Thank you! This information was extremely helpful as I was mourning the loss of my spacebar modifier and though I think hotkey setup in blender should use modo as a template (including an easily comprehendable text file that you can edit hotkeys in) I'm happy to find that part of blender's lack of functionality was just my own lack of knowledge of how its hotkeys work.

Hi Germano, hoping you might go into a bit more detail here? My confusion is such: If I create the following keymap
Window > New File
and I set it toF19 A
then this will also trigger the "select all" command. But I can't put the new keymap aboveObject Mode > (De)select All
because they are in separate branches of the keymap tree. Can you help make sense of how to implement the workaround? (is it even possible?)Added subscriber: @Rays-Lv
