• Custom Prefix: Changed from Ctrl-b to Ctrl-a for easier access
• 256 Color Support: Full color terminal support
• Mouse Support: Click to select panes and resize
• Vim-style Navigation: Vi keybindings for copy mode
• Enhanced History: 50,000 lines of scrollback buffer

• Persistent scratchpad session in popup window
• Ideal for quick notes, calculations, or temporary work
• Automatically creates session if it doesn't exist

The configuration uses TPM (Tmux Plugin Manager) with the following plugins:

• vim-tmux-navigator: Seamless navigation between vim and tmux panes
• tmux-resurrect: Save and restore tmux sessions
• tmux-continuum: Automatic session saving every minute
• tmux-yank: Enhanced copy functionality
• tmux-sensible: Sensible default settings
• tmux-themepack: Beautiful themes (using powerline/cyan theme)

Custom status bar configuration with:

• Left: Session name with tmux icon and visual separators
• Right: Time, date, and user@hostname information
• Window indicators: Custom formatting with icons

Ensure you have the following dependencies installed:

• tmux
• fzf (for interactive menus)
• lazygit (optional, for git popup)

1. Clone or copy the configuration:

   # Create tmux config directory
   mkdir -p ~/.config/tmux/scripts
   
   # Copy configuration files
   cp tmux/tmux.conf ~/.config/tmux/
   cp tmux/scripts/* ~/.config/tmux/scripts/

2. Make scripts executable:

   chmod +x ~/.config/tmux/scripts/*.sh

3. Install TPM (if not already installed):

   git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

4. Start tmux and install plugins:

   tmux
   # Inside tmux, press: Prefix + I (capital i) to install plugins

5. Reload configuration:

   # Inside tmux, press: Prefix + r

1. Start tmux: tmux
2. Create new windows: Prefix + c
3. Split panes: Prefix + + (horizontal) or Prefix + - (vertical)
4. Navigate between sessions: Prefix + w
5. Quick scratchpad: Ctrl + t

• Use Prefix + w to open the interactive session/window selector
• Sessions and windows are displayed in a tree-like structure
• Use arrow keys or vim navigation to select and press Enter

• Press Ctrl + t to toggle the scratchpad popup
• The scratchpad persists across tmux sessions
• Perfect for temporary notes, calculations, or quick commands

Edit tmux.conf and change bindings as needed. Common modifications:

# Change prefix key
set -g prefix C-a

# Add custom binding
bind-key x kill-pane

The configuration uses the powerline cyan theme. To change:

set -g @themepack 'powerline/default/blue'  # or other available themes

Both scripts accept environment variables and can be modified:

• tmux-menu.sh: Customize fzf options or session filtering
• tmux-scratch.sh: Change session name or default settings

Scripts not working: Ensure scripts are executable and in the correct path

ls -la ~/.config/tmux/scripts/
chmod +x ~/.config/tmux/scripts/*.sh

Plugins not loading: Make sure TPM is installed and plugins are installed

# Install TPM
git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm
# In tmux: Prefix + I

fzf not found: Install fzf for menu functionality

# macOS
brew install fzf

# Ubuntu/Debian
sudo apt install fzf
