How can I select text in Terminal.app using Ctrl+Shift+a and Ctrl+Shift+e? I'm on Mac OSX Catalina (10.15.3) and find that while I can use the emacs keybindings CTRLe and CTRLa to move to the end and beginning of a line respectively, I cannot use those command in combination with the SHIFT key.

My expectation would be that it would move the caret to the end/beginning of the line while selecting characters.

In other related answers I see the suggestion to move to iTerm2. However, I would like to minimise the number of "duplicate" applications on my mac.
Press ⌃ ⇧ 2 to start "marking text".
