vim Vim Registers Append to a register
Example
Yank all lines containing TODO into a register by using append operation
:global/TODO/yank A
Here, we are searching for a TODO keyword globally, yanking all lines into register a (A register appends all lines to a register).
NOTE: It is in general a good practice to clear a register before performing the append operation.
To clear a register, in the normal mode, type qaq. Confirm that the a register is empty by typing :reg and observing that a register is empty.
