What can I configure with this tmux config generator?

Every common option: prefix key (C-b / C-a / C-Space), mouse mode, base-index, history limit, escape-time, vi/emacs mode, split bindings (| and -), pane navigation, pane-resize bindings, copy-mode keys, status-bar position/colors and left/right content, terminal-overrides for true-color (Tc), and the TPM plugin block (sensible, resurrect, continuum, and more). All emitted with per-line comments.

Why does the generator ask for a tmux version?

tmux changed its styling syntax between 2.9 and 3.x. Older versions use 'set -g status-attr bold,fg=green,bg=black'; 3.x uses the unified 'set -g status-style bold,fg=green,bg=black' (and 'window-status-style' etc.). Selecting the right version makes sure your generated config loads without errors on your machine.

How does the cheatsheet reflect my custom bindings?

The cheatsheet is generated from a base set of 60+ default tmux keybindings, then overlaid with your custom choices. If you change the prefix from C-b to C-a, rebind splits to | and -, or remap pane-navigation keys, those changes show up immediately in the personalized cheatsheet so you don't have to remember which defaults you overrode.

Does the TPM plugin block include the install line?

Yes. When you enable any plugin, the generator emits the full TPM bootstrap block: the 'set -g @plugin tmux-plugins/tpm' line, each selected plugin line, and the 'run ~/.tmux/plugins/tpm/tpm' initializer at the very bottom of the config — exactly as the TPM README requires. Curated plugins: tmux-sensible, tmux-resurrect, tmux-continuum, tmux-yank, tmux-pain-control, tmux-fzf, and catppuccin/tmux.

What extra features does this tool have versus other tmux generators?

(1) Generator + live cheatsheet in one tool. (2) Per-line explanatory comments. (3) Version-aware syntax (2.9 vs 3.x). (4) Six prefix-key presets. (5) TPM plugin block with curated list (7 plugins). (6) Personalized cheatsheet reflecting YOUR custom bindings. (7) 60+ default keybindings across sessions, windows, panes, copy-mode, and config. (8) Warnings for escape-time too high, mouse mode trade-offs, nested-tmux prefix, and missing send-prefix. (9) Copy / download .tmux.conf. (10) localStorage history (max 20). (11) Shareable URL (options in fragment, never sent to server). (12) One-click presets (Minimal / Sensible / gpakosz-style). 100% offline.

# ~/.tmux.conf — generated by UnQTools (tmux-config-generator-cheatsheet)

# --- Prefix key ---
set -g prefix C-b  # New prefix is C-b. All "prefix + key" combos below start with C-b.
# --- General options ---
set -g mouse on  # Mouse on: click panes, drag dividers, scroll to copy. Trade-off: terminal text selection needs Shift.
set -g base-index 1  # Windows are numbered starting at 1 (default 0). Pairs well with keyboard 1-9.
setw -g pane-base-index 1  # Panes also start at 1 for consistency with windows.
set -g history-limit 10000  # Lines of scrollback per pane. Default-ish. Raise if you lose output.
set -sg escape-time 10  # Ms to wait after ESC before passing it through. Low — good for vim.
set -g status-keys emacs  # Key table used in the tmux command prompt (e.g. when renaming a session).
# --- Display & copy-mode ---
setw -g mode-keys emacs  # Copy-mode key table: emacs.

# --- Custom keybindings ---
bind r source-file ~/.tmux.conf \; display-message "Config reloaded."  # Prefix + r reloads this file. No need to restart tmux.
bind | split-window -h -c "#{pane_current_path}"  # Prefix + | splits the active pane vertically (left|right) and keeps the cwd.
bind - split-window -v -c "#{pane_current_path}"  # Prefix + - splits the active pane horizontally (top/bottom) and keeps the cwd.
bind -r C-up resize-pane -U 5  # Prefix + C-up resizes the pane up by 5 lines. -r allows repeat without re-pressing prefix.
bind -r C-down resize-pane -D 5  # Prefix + C-down resizes the pane down by 5 lines.
bind -r C-left resize-pane -L 5  # Prefix + C-left resizes the pane left by 5 columns.
bind -r C-right resize-pane -R 5  # Prefix + C-right resizes the pane right by 5 columns.
# --- Status bar ---
set -g status-position bottom  # Status bar appears at the bottom of the terminal.
set -g status-style fg=white,bg=black  # Status bar foreground (white) and background (black) — unified 3.x syntax.
set -g status-left "#S"  # Left side of the status bar: session.
set -g status-left-length 60  # Reserve up to 60 columns for the left segment so it isn't truncated.
set -g status-right "%Y-%m-%d %H:%M | #H"  # Right side of the status bar: datetime, host.
set -g status-right-length 60  # Reserve up to 60 columns for the right segment.
set -g window-status-current-style "bold,fg=white,bg=brightblack"  # Active window is shown bold with a contrasting background.
