Terminal Related

zellij provides a more powerful and stable terminal experience, so here is zellij's terminal shortcuts I use frequently now:

Action	Zellij's Shortcut
Floating Terminal	Ctrl + <p> + <w>
Horizontal Split Terminal	Ctrl + <p> + <d>
Vertical Split Terminal	Ctrl + <p> + <n>
Open file tree sidebar	SPC + o + p
Exit	M-x C-c

Visual Modes

The same as neovim/vim:

Action	Shortcut
Toggle visual mode	v
Toggle visual block mode	<Ctrl> + v (select a block vertically)

Text Manipulation

• Add at the end of multiple lines: :normal A<text>

  • Execublock: :A<text>

  • visual block mode(ctrl + v)

  • Append text at the end of each line in the selected block

  • If position exceeds line end, neovim adds spaces automatically

• Delete the last char of multivle lines: :normal $x

  • Execute $x on each line
  • visual mode(v)
  • $ moves cursor to the end of line
  • x deletes the character under the cursor

• Delete the last word of multiple lines: :normal $bD

  • Execute $bD on each line
  • visual mode(v)
  • $ moves cursor to the end of line
  • b moves cursor to the beginning of the last word
  • D deletes from cursor to the end of line

Search & replace

SPC s p foo C-; E C-c C-p :%s/foo/bar/g RET Z Z

1. SPC s p: search in project
2. foo: the keyword to search
3. C-; E: exports what you’re looking at into a new buffer in grep-mode
4. C-c C-p to run wgrep-change-to-wgrep-mode to make the search results writable.
5. :%s/foo/bar/g RET: replace in the current buffer(just like neovim/vim)
6. Z Z: to write all the changes to their respective files
