Vim – Using undo branches
This is a pretty neat feature that I did not know existed. I have only used u, U and CTRL-R, but a situation arose where multiple undo’s and redo’s was necessary.
:h undolist has clear documentation on how it works.
g+ Go to newer text state. With a count repeat that many times. {not in Vi} See :help g+ for more.
g- Go to older text state. With a count repeat that many times. {not in Vi} See :help g- for more.

Less – Adding line numbers
Problem:
My initial problem was how to view line numbers when using less. As I looked into this I discovered more and more ways of using less that I did not know.
Solution:
1. less -N file.txt
If you have already viewed the file then typing
-N will enable line numbers while
-n will disable line numbers.
2. To go a specifice line
g N to move upwards to a particular line. The default is 1 (ie g1) and it gets you to the first line of the file.
G N to move forward to a particular line. G alone is the default that gets you to the end of the file.
