Comment 6 for bug 496277

This happens to me in kdevelop 5.3.1. As a workaround, I copied the default shortcut scheme to a new scheme and then modified the shortcuts.

But after a few days using the new scheme, something crazy happened: Cursor keys, backspace and delete are out of function. When switching back to the default scheme (where I cannot reliably modify shortcuts) the keys work again. Very time consuming bug.
