9.8 How do I produce C-XXX with my keyboard?
============================================
On terminals (but not under X), some common “aliases” are:
‘C-2’ or ‘C-<SPC>’
‘C-@’
‘C-6’
‘C-^’
‘C-7’ or ‘C-S--’
‘C-_’
‘C-4’
‘C-\’
‘C-5’
‘C-]’
‘C-/’
‘C-?’
Often other aliases exist; use the ‘C-h c’ command and try <CTRL>
with all of the digits on your keyboard to see what gets generated. You
can also try the ‘C-h w’ command if you know the name of the command.
