How to actually hack 2x faster (terminal edition)

Here are my 6 favorite time savers:

1. Start using undo (Yes, you can undo): Ctrl-/

2. Stop spamming the up key to search previous commands
   Start using Ctrl-r then type keywords

3. Stop using clear,
   Start using Ctrl-l

4. Stop holding the left key for 10 seconds,
   Start using Ctrl-a

5. Stop holding the right key for 10 seconds,
   Start using Ctrl-e

6. Start using the built-in terminal "clipboard":
   Ctrl-a + Ctrl-k to "cut" the entire line
   Ctrl-y to paste from the "clipboard"
   After pasting, you can use Alt-y to loop through clipboard history

"But I can't remember them!"

I got you covered.

Here is how I would memorize it in a minute using mnemonics:

1. Ctrl+/: "slash" the new changes = undo
2. Ctrl+l: C+l = "Cl"ear
3. Ctrl+a: "a" is the start of the alphabet
4. Ctrl+e: "e"nd
5. Ctrl+r: "r"everse search
6. Ctrl+k: "k"ut (cut)
7. Ctrl+y: "why" does it mean paste?
8. Alt+y: "alt"er what you have pasted

The GNU readline manual (man readline) has a lot more.
Fun thing to do when you don't have the Internet.

Practice for a week and I promise you will feel invincible.
