* The keybindings of Vim
|
||
|
|
|
||
|
|
One of the things that make Vim popular is the keybindings.
|
||
|
|
|
||
|
|
| Keybinding | Description |
|
||
|
|
|------------+--------------------------------------------|
|
||
|
|
| =[m= | Go to the previous method. |
|
||
|
|
| =g~w= | Toggle letter casing. |
|
||
|
|
| =2guW= | Convert two words into lowercase. |
|
||
|
|
| =10d)= | Delete 10 sentences. |
|
||
|
|
| =39zz= | Place the cursor in the middle in line 39. |
|
||
|
|
| =3d10w= | Delete 10 words and repeat 3 times. |
|
||
|
|
|
||
|
|
Most of the time, Vim keybindings is made of mainly two things:
|
||
|
|
|
||
|
|
- *The operators denoting an action.*
|
||
|
|
- *The motions describing the scope of the action.*
|
||
|
|
|
||
|
|
There's a certain pattern to it when you use it, too.
|
||
|
|
|
||
|
|
#+begin_src
|
||
|
|
[count][operator][motion]
|
||
|
|
#+end_src
|
||
|
|
|
||
|

* Tips and tricks
|
||
|
|
|
||
|
|
- =:h= is the help system of Vim.
|
||
|
|
It contains all of the documentation of the editor and the installed plugins.
|
||
|
|
I recommend to start with the default help page (e.g., =:h=).
|
||
|
|
|
||
|
|
+ You can get the meaning of the keybinding with the help section — e.g., ~:h gg~, ~:h G~.
|
||
|
|
|
||
|
|
- Vim has fine-grained control motions.
|
||
|
|
+ =(= and =)= for sentences.
|
||
|
|
+ ={= and =}= for paragraphs.
|
||
|
|
+ =[= and =]= for sections.
|
||
|
|
|
||
|
|
- There are many advanced navigation features in Vim.
|
||
|
|
+ =gf= will go to the file at point.
|
||
|
|
+ =K= goes to the definition of the keyword at point.
|
||
|
|
+ =Ctrl+O= will jump back at a previous jump point.
|
||
|
|
+ =gd= go the local definition of the keyword at point.
|
||
|
|
+ =H=, =M=, and =L= places the cursor in higher, middle, and lower part in the current screen, respectively.
|
||
|
|
+ =zt=, =zz=, and =zb= displays the current line in the top, middle, and bottom part of the screen, respectively.
