commit 20a9c7a38184c10b95ed0fca7dfc6728425ea418
Author: Guillaume Munch <[email protected]>

Fix SIGSEGV when introducing a new shortcut (#9869)
removeShortcut() restores default settings, therefore was used incorrectly.
I
introduce deactivateShortcuts() which only removes assignments.
Clean up a bit the lack of view / model distinction (getting rid of the
crashing
code at the same time).
Repair inconsistency of the selection in the "modify" case. (regression at
717d19d3c)
Make the test for existing bindings a bit more robust. (Not perfect yet.)
Focus on the item that has just been added/modified. (cosmetic)
