I there an easy way to get to the end of all lines when in column mode?

So say I have ten lines and I need to add something to the end of all ten of them and they are all different lengths.

I have used other editors and they do seem to be able to do it but you have to follow a specific sequence to get it to work.

Thanks in advance!

Turns out Edit > More line operations > Insert text on each line... works with column mode, too (exactly the way it would work w/o column mode):

that is what I was looking for. Though there might be a magical selection and key stroke but I can make this a hotkey.

Thanks!
