Smooth typing deletion
I revisited an old topic of user typing in blueprints, and fixed up my Backspace event so I don't have jumpy text deletion in the current line.
In this example the BackspaceSpeed float gets faster (up to a point) the longer you hold down the Backspace key. This means that if you just tap the key, you just remove one character. If you hold it, it'll remove characters smoothly and quickly.
