+useful to have the duplicates working outside of emacs. AppScreen
+modifier means that the keybind only works within a program like emacs
+which takes over scroll back, per

+Historical note about change no longer in ian.keytab:
+I saved that in case konsole updates the defaults, which
+happened. Originally saved in 2019, to fix control-backspace not working
+because it wasn't bound to anything, it just emited backspace. I fixed
+it by setting it to ^W, because bash binds ^W to unix-word-rubout. But in 2023 I ran profanity which uses
+readline, and control-backspace didn't work. Poking around, I figured
+out that konsole defaults had been updated to make control-backspace emit ^H, and sakura worked the same, detected by running
+running "stty -icanon; cat" per
+http://www.linusakesson.net/programming/tty/index.php . So, it seems better to set ^H to unix-word-rubout in .inputrc than change the key in konsole.
