VIM Installation is pretty simple and straightforward but there are a few points you need to pay attention to, to ensure a 100% successful installation.

vim from any command prompt in your computer and proceed to initiate a brand new file. Below, launching vim to open a specific Python file (or any other code or text file) is also explained.
Launching VIM (From command prompt)
- First launch a Command Prompt you prefer. It can be:
- Windows Command Prompt
- Anaconda Command Prompt
- Navigate to the directory you want to edit files at. Using cd and/or cd..
- Open Python file with following command:

First time in VIM (Main modes and functions)
Now you’ve already installed VIM and managed to enter the program. You’re pretty much there with starting to use VIM as you wish. However, there are a few concepts that might seem confusing if it’s your first time with VIM.
First of all you won’t be able to type or edit anything when you first launch VIM. Don’t worry it’s easy to get there. This is because there are 2 modes in VIM:
- Command Mode
- Editor Mode
You’ll know you’re in command mode if it doesn’t say –INSERT– at the bottom or if the cursor is blinking at full character height.
You’ll know you’re in editor mode if it says –INSERT– at the bottom or if the cursor is blinking only as a little underscore.
- You can switch to Editor Mode by pressing “
- You can switch back to Command Mode by pressing “
You need to be in Editor Mode to be able to type code or modify existing code.
VIM Basic Commands
You can switch to Command Mode to be able to type commands such as “Save”, “Quit”, “Save and Quit” etc. Commands always start with colon “:” Here are some examples:
:q >>> Quits
:w >>> Saves
:wq >>> Saves and Quits

A : Appends at the end of the line
o : New line
u : undo
x : deletes character
dw : deletes until the next word
dd : deletes line (also saves to clipboard)
p : pastes
:wq : writes and quits
:x : writes and quits
:w filename : writes a copy of the file as filename
:q! : quits without saving even if changes were made!
:help : display help
: Tab completion, shows all commands, use right-left keys to navigate once bottom menu pops up.
/someword : searches (replace someword with your query)
- If you press “*” key while on a word, it will search for the word under the cursor in the entire document and highlight the results. (# key can also be used for same purpose)
- n or N can be used to navigate through the search results (backwards and forwards)
- You can also type “/” in command line to initiate a search by typing your query.
