Ok, this is probably simple to do, but I just can't find how.
When opening a file in emacs, I use:
C-x C-f. Which then drops me down into the command buffer with the current path already filled out.
In previous setups (other companies), I could just hit
/ and it would eliminate the current path, replacing it with the root directory
/. Or, I could hit
~, and it would similarly clear out the path, going to my home directory
In my current setup, I do not have that feature. I would like to turn that on.
