Typing reversed in world editor

Seriously frustrating bug: With no discernable cause, the text fields in world editor spontaneously enter a mode where the cursor moves to the left of the field, and cannot be placed at the end of a string. The result is that anything I type ends up backwards.

The only way I've found to solve this is to exit world editor, then exit the game.

 

Solution: learn how to type backwards

 

I'm wondering if it's an errant keystroke. I know that occasionally the left rotation will get stuck while I'm navigating, and I have to hit the NumPad 4 again to un-stick it. I've verified that I don't have the Sitcky Keys shortcut turned on, but I also saw settings for Toggle Keys and Filter Keys (WTF, Microsoft, just let me use my #$^%& keyboard!). I've got their keyboard shortcuts turned off too, so we'll see if that makes a difference.

 

Those keyboard shortcuts are really a pain..
If I have to spam Shift to sprint in a game, Call of Duty for eg, boom, stick keys notifications. Like sheesh.
Yeah, best to turn all that off lmao
