If somebody still have problem to get "-"-char or F11 with Pinephone Keybooard, this AltGr layout helps:

if image doesn't work here is direct link: https://codeberg.org/aLilyBit/ppkb-l...altgr-pine.svg

I just did:
git clone https://codeberg.org/alilybit/ppkb-layouts.git
cd ppkb-layouts
sudo ./install-xkb.sh
setxkbmap pp altgr

More about these Pinephone layouts found here: https://codeberg.org/aLilyBit/ppkb-layouts
I think that at least this layout should merge to next Leste version.

EDIT: btw. You can now get all chars that virtual keyboard has so you might like get it off: Just untick Setting - Text Input - Use Virtual Keyboard. Now you can select text in X Terminal with finger without annoying virtual keyboard pop-up.
EDIT2: BUT, there is one problem to solve, after reboot I have to write setxkbmap pp altgr again. How to fix this?
