Key Map

Notice

• Since I want the focus of the vim keymap. So I configure not to use arrow keys, I use h, j, k, l to move the cursor. But it applies to normal mode, insert mode you can use arrow keys.

Leader key

• This is key usually we use in vim if you apply my config
• Default is key , on keyboard

Use leader key

• , e => Find file all current folder
• , v => Split vertical screen
• , h => Split horizontal screen

Control key

• This upgrade with normal key in my config
• Note: Control key in here apply for Linux and Macbook. Which is mean on macbook you not convert to command key

Use control key with normal mode

• Ctrl b => Open sidebar
• Ctrl h => Move left screen
• Ctrl j => Move bottom screen
• Ctrl k => Move top screen
• Ctrl l => Move right screen
• Ctrl n => Move next character like cursor here
• Ctrl t => Open terminal

Use control key with visual mode
