# Alternative Terminal Stacks + Universal Vim Keybindings

---

## PART A — Alternative Stacks Comparison

| Feature | Ghostty+tmux (Current) | WezTerm | Zellij | Kitty+tmux | Alacritty+tmux | Warp | Rio |
|---|---|---|---|---|---|---|---|
| Built-in Multiplexing | No (needs tmux) | Yes | IS the multiplexer | No | No | Yes | No |
| Performance | **Fastest** (2-5x faster) | Good, heavier | Good (Rust) | Excellent | Excellent | Good | Fast (WebGPU) |
| macOS Native Feel | **Best** — Metal renderer | Cross-platform | Good | Own window mgmt | Minimal UI | Polished but SaaS | Cross-platform |
| Config Style | INI key=value | Lua scripting | YAML/KDL | Single file | TOML | GUI + config | TOML |
| Keybinding Philosophy | tmux prefix-key model | Custom Lua | **Modal (like Vim!)** | tmux prefix-key | tmux prefix-key | Modern shortcuts | Standard |
| Beginner-Friendly | Medium | Medium | **Best** — keybinding bar | Medium | Medium-Low | High | Low |
| AI Integration | Claude Code (external) | None | None | None | None | **Built-in agents** | None |
| Stars/Maturity | 45K+, launched Dec 2024 | Mature, large community | Growing, active | Since 2017 | Mature, stable | VC-funded, SaaS | Early-stage |

### WezTerm
**Best if:** you want to eliminate tmux entirely and need cross-platform (including Windows).
**Trade-off:** 2-5x slower than Ghostty, Lua learning curve.

### Zellij
**Best if:** you're a beginner or modal-thinking developer. Context-aware keybinding bar shows available actions — lowest learning curve.
**Watch out for:** Neovim mode conflicts — install [zellij-autolock](https://github.com/fresh2dev/zellij-autolock) plugin.

### Kitty
**Best if:** you need deep scriptability or the richest TUI/image ecosystem.
**Watch out for:** Less native macOS feel, no Windows support.

### Alacritty + tmux
**Best if:** you need Windows support or have existing dotfiles.
**Watch out for:** Won't add tabs/splits by design. True-color with tmux+Neovim requires config work.

### Warp
**Different category — ADE, not a traditional terminal.**
Mandatory login, $15/month, no tmux compatibility, closed source. Not suitable for Vim-centric keyboard-driven workflow.

### Stack Decision Matrix

| If you want... | Choose... |
|---|---|
| Best macOS native + performance | **Ghostty + tmux** (current) ✅ |
| Eliminate tmux entirely | **WezTerm** |
| Easier multiplexer for beginners | **Ghostty + Zellij** |
| Maximum scriptability | **Kitty** |
| Proven + Windows support | **Alacritty + tmux** |
| AI-first, less keyboard-driven | **Warp** (SaaS trade-offs) |

## PART B — Universal Vim Keybindings (Never Change)

### The Grammar Rule
Vim uses **Verb + Noun** grammar. Works identically in: Vim, Neovim, LazyVim, VSCodeVim, IdeaVim, Zed, XCode.

Sources: [Vim Grammar](https://learnvim.irian.to/basics/vim_grammar/) · [The Vim Language](https://www.ssp.sh/brain/vim-language-and-motions/) · [freeCodeCamp Vim Explained](https://www.freecodecamp.org/news/vim-language-and-motions-explained/)

### Core Motions (100% Universal)
| Motion | Action |
|---|---|
| `h` `j` `k` `l` | Left / Down / Up / Right |

| `0` / `$` / `^` | Start / End / First non-blank of line |
| `gg` / `G` | First / Last line |

| `gu` / `gU` | Lowercase / Uppercase | `guiw`, `gUU` |

### Text Objects (100% Universal)
Work with `i` (inner) and `a` (around):
`ciw` `ci"` `ci(` `ci{` `ci[` `ci<` `cit` — change inside word/quotes/brackets/tag
`diw` `di"` `di(` — delete inside
`yiw` `yi"` `yi(` — yank inside
`daw` `da"` `da(` — delete around (includes delimiters)

### Insert Mode (100% Universal)
`i` / `a` / `I` / `A` / `o` / `O` / `s` / `S` + `Esc` to return

### Search (100% Universal)
`/pattern` forward, `?pattern` backward, `n`/`N` next/prev, `*`/`#` word under cursor

### Marks (100% Universal)
`m{a-z}` set mark, `` `{a-z} `` jump exact, `'{a-z}` jump to line

### Registers (100% Universal)
`"{a-z}y{motion}` yank into register, `"{a-z}p` paste, `"0` last yank, `"+` system clipboard

### Macros (100% Universal)
`q{a-z}` start recording, `q` stop, `@{a-z}` play, `@@` replay last

### Visual Mode (100% Universal)
`v` char, `V` line, `Ctrl-v` block, `gv` reselect, `o` toggle selection end

### Dot Repeat (100% Universal)
`.` — repeat last change. One of the highest-leverage motions in Vim.

### NOT Universal (editor-specific)
- `:commands` (Ex commands) — varies by editor
- `Ctrl-w` splits — each editor handles differently
- Buffer/tab navigation — editor-specific
- Plugin mappings (`gcc`, `cs"'`) — need plugin support

### The 30-Command Beginner Safe List
```
MOVEMENT:   hjkl  w/b  e  0/$  gg/G  Ctrl-d/u  f{c}/t{c}  ;/,  %
EDITING:    i/a/I/A/o/O  Esc  dd/yy/p  u/Ctrl-r  .
TEXT OBJS:  ciw  ci"  ci(  diw/di"/di(  yiw  daw/da"
SEARCH:     /pattern  n/N  *
POWER:      q{a-z}...q  @{a-z}  v/V/Ctrl-v
```
