Introduction

Neovim is one of those apps I actively add new features to then strugle to remember them due to my lack of muscle memory for it. But when I do want to use them I forget what the keymap is. I'd then have to go through my config files to find out the shortcut, which is inconvenient.

Here I am going to document everything I should be needing here so that I can read them when I get the intuition that I forgot something useful.

General

• vU uppercase selection.
• vl lowercase selection.
• . redo last action.
• gl and gh to go to start and end of the line.
• ]<space> and ]<space> to add empty line in the next or previous line.
• vuw and vuW to select current word.
• vup to select current paragraph.
• vu[some symbol like "] to select content within those symbols under context of the cursor.
• N and E to scroll down and up.
• :new to open a file in another window.
• <space> + [hnei] to move cursor to another window.
• <space> + [HNEI] to move the current window.

Deleting Stuff

• Normal mode

Substitution

This editor's text replacement feature is accessed via :substitute or :s

• Selecting lines then doing : will insert something into the command line. Those characters help the command understand that you want to execute it in only the selected area.
• They use regular expressions to match stuff.
• :%s/hello/hwello this will replace first "hello" in every line of the file. % selects the entire file.
• :%s/hello/hwello/g this will replace all "hello" of the file. % selects the entire file. /g will apply it to every match rather the first one in a line.
• :%s/^/something this will add "something" to the start of every line.
• :%s/$/something this will add "something" to the end of every line.
