### Changes and Rationale:

1. **Vim-style Key Bindings**: Retained for copy-mode and status-line interactions.

2. **Pane Navigation**: Changed to use `Alt` (`M-`) combined with `h/j/k/l`. This reduces potential conflicts with NeoVim's keybindings.

3. **Pane Resizing**: Also uses the `Alt` modifier to align with the pane navigation scheme.

4. **Mouse Support**: No change, as it's essential for a seamless experience.

5. **NeoVim Integration**: The shortcut for opening NeoVim in a new window (`prefix + e`) remains the same for convenience.

6. **Status Line and Pane Border Colors**: Unchanged, as they are primarily aesthetic.

After updating your `~/.tmux.conf`, reload the configuration in an active tmux session with `tmux source-file ~/.tmux.conf`. 

Next, you can share your current NeoVim configuration, and we can align it to complement your tmux setup, ensuring that the two tools work together harmoniously.

now provide me a cheatsheet for tmux for all my key-bindings and how to use tmux like starting sessions, getting layouts configured etc.
ChatGPT
Certainly! Below is a concise cheat sheet for tmux, focusing on your customized key-bindings and essential commands for managing sessions, windows, panes, and layouts.

### Starting and Managing tmux Sessions

- **Start a New Session**: `tmux` or `tmux new -s [session-name]`
- **List Sessions**: `tmux ls`
- **Attach to a Session**: `tmux attach -t [session-name]`
- **Detach from a Session**: `Ctrl-A` then `D` (while in tmux)
- **Kill a Session**: `tmux kill-session -t [session-name]`

### Working with Windows

- **Create a New Window**: `Ctrl-A` then `C` (capital C)
- **Open NeoVim in New Window**: `Ctrl-A` then `e`
- **Switch to Window by Number**: `Ctrl-A` then `[window-number]`
- **Rename Current Window**: `Ctrl-A` then `,`
- **Close Current Window**: Close all panes or `exit` from shell

### Pane Management

- **Split Pane Horizontally**: `Ctrl-A` then `"`
- **Split Pane Vertically**: `Ctrl-A` then `%`
- **Navigate Between Panes**: `Alt` + `h/j/k/l`
- **Resize Panes**: `Alt` + `Arrow keys`
- **Toggle Pane Synchronization**: `Ctrl-A` then `C-s`
- **Close Current Pane**: `exit` from shell in that pane

### Copy Mode and Scrolling

- **Enter Copy Mode**: `Ctrl-A` then `[`
- **Navigate in Copy Mode**: Vim-style navigation (`h/j/k/l`)
- **Scroll Up/Down**: `Ctrl-A` then `[`, then `PageUp/PageDown` or `Ctrl-B/Ctrl-F`

### Miscellaneous

- **Reload tmux Configuration**: `Ctrl-A` then `r`
- **Cycle Through Panes**: `Ctrl-A` then `C-o`
- **Show Shortcuts and Key Bindings**: `Ctrl-A` then `?`

### Customizing Layouts

- **Switching Layouts**: `Ctrl-A` then `Space` cycles through pre-set pane layouts.
- **Saving Custom Layouts**: tmux does not have a native layout saving feature, but you can script layouts or use plugins like `tmux-resurrect` or `tmuxinator` for more advanced layout management.
