If you assign the keyboard shortcuts dynamically can you please ensure that you don't clash with existing keyboard shortcut customisations already created by the user.
That's happened to me at least once and maybe twice in the past with Sigil. I've not reported it because its easily fixed at my end, hence I can't recall the details. I just find what took it (by sorting on the shortcut) and change it, normally to nothing, and reinstate my original usage of the shortcut.
Sigil's not the only program that's done this to me, but its 'sort by shortcut' feature makes it less onerous to fix than some other programs, and I'm thankful for that. In another instance I had to sweet-talk a plug-in developer into adding a blade to his swiss army knife gadget, the extra blade creates a CSV file of keyboard shortcuts I can use to find the clashes
