Choose the layer where the shortcut runs. Alacritty, the terminal application, sends many macOS-style shortcuts directly to tmux; fish adds command-line bindings; tmux commands use Ctrl + A as their prefix.

macOS system shortcuts

These mappings are applied by the system_defaults Ansible role.

Shortcut	Action
`Cmd`+`G`	Open Spotlight
`Cmd`+`Space`	Select the next input source

The default shortcut for selecting the previous input source is disabled so it does not conflict with the configured next-source binding.

Alacritty and tmux

These shortcuts work from Alacritty without first entering the tmux prefix.

Windows and sessions

Shortcut	Action
`Cmd`+`N`	Open a new Alacritty window
`Cmd`+`T`	Create a tmux window in the current directory
`Cmd`+`Shift`+`R`	Rename the tmux session
`Cmd`+`W`	Kill the current tmux window
`Cmd`+`X`	Kill the current tmux pane

Shortcut	Action
`Ctrl`+`Tab`	Select the next tmux window
`Ctrl`+`Shift`+`Tab`	Select the previous tmux window
`Cmd`+`1` … `Cmd`+`9`	Select tmux window 1–9
`Cmd`+`F`	Enter copy mode and search forward
`Cmd`+`0`	Reset the Alacritty font size

Links and text

Shortcut	Action
`Ctrl`+`Shift`+`O`	Open a URL or path under the pointer: URLs go to the system opener, files open in a new tmux Neovim window
`Cmd`+`Shift`+`P`	Copy a visible file path, including its line number when one is present
`Shift`+`Enter`	Send a Shift-modified Enter that a TUI can tell apart from plain Enter

fish shell

These bindings act on the current fish command line.

Shortcut	Action
`Alt`+`S`	Prepend `sudo` unless the command line already starts with it
`Ctrl`+`G`	Open the project chooser powered by fzf
`Ctrl`+`T`	Open the fzf directory picker
`Alt`+`Left` / `Alt`+`Right`	Move the cursor one word backward or forward

Alacritty sets option_as_alt = "OnlyLeft", so the Alt bindings above use the left Option key. fzf runs with --tmux, so its pickers open in a tmux popup whenever one is available. The fzf.fish plugin installs further pickers on its own default keys.

tmux prefix commands

Press Ctrl+A, release it, and then press the command key. Press Ctrl+A twice to send a literal Ctrl+A through to the program in the pane.

Prefix Ctrl+A then release

Create and arrange

Command	Action
`Ctrl`+`A` then `c`	Create a window in the current directory
`Ctrl`+`A` then `r`	Rename the current window
`Ctrl`+`A` then `R`	Rename the current session
`Ctrl`+`A` then `\|`	Split the pane horizontally
`Ctrl`+`A` then `_`	Split the pane vertically
`Ctrl`+`A` then `+`	Toggle pane zoom
`Ctrl`+`A` then `m`	Move the current window to a prompted index
`Ctrl`+`A` then `L`	Link a window from another session

Move around

Command	Action
`Ctrl`+`A` then `h` / `j` / `k` / `l`	Move one pane left, down, up, or right
`Ctrl`+`A` then `[` / `]`	Select the previous / next pane
`Ctrl`+`A` then `{` / `}`	Select the previous / next window
`Ctrl`+`A` then `Tab`	Return to the most recently used window
`Ctrl`+`A` then `\`	Swap the current pane with pane 1, or select pane 1
`Ctrl`+`A` then `Ctrl`+`O`	Rotate the panes downward

Agentic tasks

Command	Action
`Ctrl`+`A` then `Ctrl`+`G`	Start or reopen an agent task: pick a repository, name the task, get a git worktree with an OpenCode window
`Ctrl`+`A` then `S`	Create or attach a context session by name, then open the task launcher
`Ctrl`+`A` then `Ctrl`+`D`	Open the workmux agent dashboard

Close and detach

Command	Action
`Ctrl`+`A` then `x`	Kill the current pane
`Ctrl`+`A` then `X`	Kill the current window
`Ctrl`+`A` then `Ctrl`+`X`	Confirm and kill every other window
`Ctrl`+`A` then `Q`	Confirm and kill the session
`Ctrl`+`A` then `d`	Detach this client
`Ctrl`+`A` then `D`	Detach other clients when present

Configuration and copy mode

Command	Action
`Ctrl`+`A` then `Ctrl`+`E`	Edit `tmux.conf`, then reload it
`Ctrl`+`A` then `Ctrl`+`R`	Reload `tmux.conf`
`Ctrl`+`S`	Enter copy mode without the prefix
`Ctrl`+`A` then `p`	Paste the latest tmux buffer
`Ctrl`+`A` then `Ctrl`+`P`	Choose a tmux buffer

Copy mode uses vi keys and supports the mouse wheel, Page Up and Page Down, and Option-based scrolling by line or half page.

Neovim additions

LazyVim provides most editor mappings. This repository overrides or adds the following:

Mode	Shortcut	Action
Normal	`o`	Create a blank line below without staying in Insert mode
Normal	`O`	Create a blank line above without staying in Insert mode
Normal	`<leader><leader>`	Clear search highlights
Normal	`ys` / `ds` / `cs`	Add, delete, or replace a surrounding pair
Normal and Visual	`<leader>/`	Comment the current line or the selection
Normal and Visual	`<S-h>` / `<S-l>`	Move the line or selection left or right
Normal and Visual	`<S-j>` / `<S-k>`	Move the line or selection down or up
Normal and Visual	`gz`	Title-case the line or the selection
Normal, Operator, and Visual	`w` / `b`	Step by subword, so `camelCase` and `snake_case` split into parts
Visual	`>` / `<`	Indent or outdent while keeping the selection active
Insert	`<C-j>` / `<C-k>`	Select the next or previous completion item

Three LazyVim defaults are removed rather than remapped: <C-s> for save in every mode, and the fzf-lua pickers on <leader><space> and <leader>/. The second of those keys is reused for commenting above.

OpenCode

These act inside the OpenCode TUI, so the tmux prefix is not involved.

Shortcut	Action
`Ctrl`+`R`	Record a voice prompt, transcribe it, and insert the cleaned text

Ctrl+R is OpenCode’s factory binding for renaming a session. The managed tui.json disables that binding so the voice plugin can own the key; rename a session with the /rename command instead.
