Boost Your Terminal Productivity: Advanced tmux Copy‑Paste and Shortcut Hacks

Enable vi‑mode selection in tmux

Add the following lines to ~/.tmux.conf so that tmux uses Vim‑style visual selection for the pane buffer:

set-window-option -g mode-keys vi
bind-key -t vi-copy 'v' begin-selection
bind-key -t vi-copy 'y' copy-selection

Reload the configuration. Enter copy mode with Ctrl+b [, start selection with v, move the cursor using Vim navigation keys, copy with y, and paste at the cursor with Ctrl+b ].

One‑stroke shortcuts without the prefix

Typical tmux commands require the prefix ( Ctrl+b) before each key. By mapping commands directly to their ASCII‑hex codes you can invoke them without the prefix. For example, Ctrl+b corresponds to hex 0x02. Create custom key bindings that send the appropriate hex codes to tmux, allowing single‑key shortcuts for common actions. Refer to an ASCII‑hex table to determine the codes for other keys.
