Hi -
I was looking for the same change as the original poster: column 1 only for HOME key.
This thread helped.
Your replies helped me to find the key-bindings window, which I fiddled with for a bit.
Originally I was looking in the general options windows, but couldn't find anything.
You know, there are so many options and settings,
it would be cool if you could SEARCH within them on a keyword like "home key"...
In the key-bindings window:
I didn't realize it at first, but (for future readers) you can show the current binding for a given key sequence
by clicking the "Add Key..." button and then hitting the key sequence. In this case, HOME.
Then (if you wanted) you can look up the command it shows you in the command list, and unbind it.
Now you can create the new binding you want.
(the "Add key" button threw me at first because I didn't want to "ADD" a binding, I wanted to undo one...)
But I tried just giving it a new binding, and it turns out it got rid of the previous binding. So the "unbind" may not be necessary.
Then I noticed it was even easier to pick "Redefine common keys" instead of "key bindings":
It shows you the two common options for the HOME key and you can pick what function you want it to use.
I have now bound alt-Home to the begin_line_text_toggle().
thanks,
Pete
