Programming

Kids these days….

These Ctrl keys are shortcuts from Emacs - there's a Bash settings to switch to vi-mode if you so wish. Anyway, the first Emacs was written in 1981, probably on a PDP-11, which did not have Home and End! Same reason Neovim uses "yank" instead of "copy". ctrl-c/ctrl-v did not exist as a shortcut back when vi was being written!

I know you didn't intend to be mean or anything, but maaaaaan kids these days don't know their history (not entirely your fault, btw)😆

This tip is super useful to me because not everyone is using a PC. On a PC sure, I would use the Home and End keys all the time. Now I'm using a laptop as my main computer and the Home and End keys are in a weird position that even to this day, 4ish years of laptop use, I still have to actually look at the keys to find them.

That's horrible for muscle memory, every time I switch desk/keyboard I have to re-learn the position of the home/end/delete/PgUp/PgDn keys.

I got used to Ctrl-a / Ctrl-e and it became second nature, my hands don't have to fish for extra keys, to the point that it becomes annoying when a program does not support that. Some map Ctrl-a to "Select all" so, for input fields where the selection is one line, I'd rather Ctrl-a then left/right to go to the beginning/end than fish for home/end, wherever they are.

That's a new one for me. Thanks!

But that's more key presses than just using existing keys

I use dtach for this feature

I should've just looked it up but got lazy to be honest.

I use Dreamhost to connect to IRC support channels using irssi. I go through Dreamhost since it hides my home IP address. It disconnects me frequently. This would be very useful.

Thank you for the info.

I have fzf-git for all of that, but honestly I don't ever use it, as I'm hardly ever switching between branches and tab complete is enough for me in most cases.
