How can I replicate Windows End/Home key? How can I replicate Windows Home/End keys to use to jump to the end of a line or use Shift to highlight to the end or start of a line
I used the following a lot.

⌘CMD+ꜛ: Home

⌘CMD+↓: End

⌘CMD+←: Beginning of Line

⌘CMD+→: End of Line

These I learned the other day from here - very handy for coding and writing, these are emacs bindings which work on Macs.

CTRL+A: beginning of line.

CTRL+E: end of line.

CTRL+U: delete from cursor to beginning of line.

CTRL+K: delete from cursor to end of line.

CTRL+W: erase word to the left.

CTRL+T: transpose characters around cursor.
