@2fd7551e I don't know if you can paste an Enter -- I think it depends on your terminal app and your shell (note that if you copy two lines, like
echo hello
echo world
and paste them, some terminal apps and some shells will execute the first line before pasting the second, and some won't until you hit enter). You can also hit Ctrl-X Ctrl-E to open up a text editor to type a command, which is then executed when you save with no enter key required, but... you probably can't paste the ^X^E keys either 

 @b214e325 My keyboard doesn't work - so I can't hit CTRL 🙂 

I'm using bash in Gnome Terminal. 

 @2fd7551e yeah, that's what I figured. On-screen keyboard, maybe? Although that's avoiding the problem rather than solving it 

 @b214e325 OSK could work - if I could figure out how to launch it without a keyboard
