Practical neovim

Objectives

Minimalistic approach (I don't want to spend 10000 hours to become a neovim guru):

• Learn minimal set of commands to reduce cognitive load.
• Install least number of plugins for the simplest configuration (avoid them as much as possible).
• Easy switch to bare vi when needed.

Navigation

Quick navigation in the current line:

• Search for the word you want to go to: /<word> (forward) or ?<word> (backward), press and n. If you set hlsearch and want to quickly unhighlight, you can add nnoremap // :nohlsearch<CR> to your init.vim file. Then you can double press // to unhighlight search.
• Use f/t or F/T commands and ; to repeat the move. f<space> can be very convenient here.

I prefer this instead of w/b. This helps me keep the minimum number of commands in my muscle memory. I don't have to think which command is the best. I always use the same for all kind of things. The f/t is very useful in conjunction with d/c commands and . to repeat.

• Jump to previous edit locations: g; (or just the last one with `., but why should I remember this one).
• Jump forward to edit locations (in case you went to far with g;): g,.

Scroll

• zz - move current line to the middle of the screen.

• zt - move current line to the top of the screen.

• zb - move current line to the bottom of the screen.

• Ctrl-e - scroll one line down, constant pressing works.

• Ctrl-y - scroll one line up, constant pressing works.

Less usefull to me:

• Ctrl-d - scroll down half screen, constant pressing works.
• Ctrl-u - scroll up half screen, constant pressing works.

I never use page down/up (Ctrl-b/Ctrl-f). If I then want to move the cursor to a specific line after scrolling, I use: <n>G (set number must be set in init.vim).

Modify

• cc - replace current line.
• C - replace to end of line.

Delete

Normal mode:

• x - delete current character.
• X - delete previous character.

Insert mode:

• BACKSPACE - delete previous character.
• Ctrl-w - delete previous word.

Copy / Paste

• Ctrl-r" - Paste content of last y/d/c command.

Search and Replace

Search modifiers:

• g - whole document.
• c - confirm replacement.
• I - case sensitive.
• \<word\> - whole word only.

Useful tips:

• s// - search previous pattern.
• * - search word under cursor; then use :%s//<replacement>/gI to replace in the whole document.
