Often when I'm typing out a text using the physical keyboard, I'll make a typo and hit the backspace to delete the last letter I typed. But sometimes when I hit backspace it will instead delete a whole block of text, maybe 10 words or so. It's annoying because I can't undo the delete, as far as i can tell, and just have to re-type the text. I haven't been able to figure out if I'm accidentally doing some kind of undo or block delete shortcut (admittedly I have what they call stupid fingers, hence the whole reason I wanted a physical keyboard), or if it's just a glitch. Anybody else have this problem?
