Registers

Register is the clipboard for vim. It is actually more than that. Registers could be number, letter, etc. You could find possible registers by using :help registers.

"kyy                    - yank current line to register k
"ky                     - yank selected region to register k
"kp                     - Copy register k to after current position
"kP                     - Copy register k to before current position
:reg                    - Show all registers
:let @a = "testing let" - set the register a as text 'testing let'

Record and Playback

Record and playback is very powerful. It will speed up the whole editing work.

qb   - record typed characters in to register b
qB   - append typed characters in register b, 
       record only supports lower case letter as register name.
q    - stop recording
@b   - execute the content of register b
@@   - repeat the last executation.
6@@  - repeat 6 times.
15@b - Execute the content of register b 15 times
