How to clear selection in OS X Terminal? Usually in Terminal to delete text you have to sit there for an hour holding the ⌫ Delete. This is particularly annoying since I use vim in the terminal for Text file editing. 



But anywhere else in OS X or any computer since 1988 really you can just select text and delete. Not in terminal. 

I know terminal isn’t meant to be the latest in computing, but batch deletion of text is really essential. How do I fix this? Also, yes, I know about ⌥ Option⌫ Delete to delete full words. Still it's no bueno for text editing.

How can I delete whole lines of selected text?
You need to learn the keyboard commands for the editor you are using; in this case, vim.  

To delete, press Esc for "Command Mode" then....


x -  for a character
dw  - for the current word
dd  - for the current line
5dd -  for five lines


Terminal isn't a GUI environment so mouse interaction is minimal.  See Vim Help Files for full documentation on how to use Vim.

(I personally prefer nano as it's much more user friendly and included with macOS)
