Say I open a file in vim. I start on line 1 column 1 and hold down j until I am on line 14. Pressing :7CR puts me on line 7. I press yy to "yank".
How do I return to line 14? Using CTRL + o takes me back to the top of the file. ` ` gives me the same results.
You can type 7G to jump to line#7, then type Ctrl-o to jump back.
:set showcmd
to show what you have typed at the right bottom.
To yank line#7 (No cursor moving):
:7y
To paste line#7 below line#14:
:7t14
