C-- shrinks the font size depending on the console.

To run the universal-argument command I map the C-u to somewhere else
as the fingers more frequently use C-u for rubbing out from the
current position to left margin position zero. I use Super-u or
Escape-u for universal-argument and avoid that if I can because Super
and Escape are read differently depending on console and keyboard
context.

I agree.  I guess we could use C-x O for now until something more
preferable comes along to occupy the big O. org-mode?  That fits
nicely next to project.

Perhaps there could be a minor mode to flip the switch on C-u and C-h
behavior.  Rolling your own C-u and C-h behavior breaks functionality
for example to find completions to C-x p using

 <f1> c C-x p <f1>

doesn't do what the default C-h does I guess

 <f1> c C-x p C-h ; or TAB, I guess wrong there too

The fallback is to search the output from <f1> b or the
describe-bindings command for C-x p.
