Steam deck link items and on screen keyboard issues

Hello I currently have two issues while playing the game on steam deck

  1. you can’t link items by default
  2. in game on screen keyboard can type most keyboard symbols

for issue one you can set up a button cord macro or assign back buttons to keys and track pad to RMB. Which i had to goggle how to do and use other posts from other games to figure it out, which is not an ideal situation. And recently that has stopped working for me

For issue two i tried to contact support on steam deck but couldn’t as the in game on screen keyboard does not have access to the @ symbol. I tried to use the integrated steam deck OSK but the interface takes you out of the email line and prevents me from using the work around. this caused me to have to log onto pc to write this.
