Vim Tricks

Learning vim

There are many ways to get familiar with vim

1. If you have vim installed then there is a cli command called vimtutor which you can use to learn vim. For begineers i would recommend that you complete it till 2nd chapter.
2. Similarly foe neovim you can use the command from inside neovim with entering command mode with : and then tutor.
3. Evil Tutor ( Vim tutor for emacs users )

Move by word

Word is anything seperated by punctuation or space.

normal Mode:
w,W     : Go forward by one word

b,B     : Go back by one word

Fast move to char in line

Cursor goes from | to ^

normal Mode:
f     : Goto the char
# Press fw on this line will go here
#          |            ^

F     : Goto the char ( Backward )
# Press Fw on this line will go here
#                       ^       |

t     : Goto just before the char
# Press tw on this line will go here
#          |           ^

T     : Goto just after the char ( Backward )
# Press tw on this line will go here
#                        ^         |
