At times, my software (generally while testing) outputs very long lines, so I use the -S command line option which means I see one line instead of possibly many screens of data.
Once in a while, I like to verify that data which means I scroll right through the very long (wide) line.
Once I'm done, I'd like to be able to come back to column 1 with a key. I tried 0 and 1 and ^ (i.e. like in vim) but it doesn't look like that works. I'm thinking that there may not be a way even though you'd think that's an important feature...
