## Window Navigation

Move between windows with:

```vim
<C-h> left
<C-j> down
<C-k> up
<C-l> right
```

Cycle through windows:

```vim
<C-w>w
```

## Terminal

Leave terminal mode and return to normal mode:

```vim
<Esc>
```

## LSP

Mason is installed through `vim.pack` together with `mason-lspconfig.nvim` and `nvim-lspconfig`.

This config automatically installs and enables the managed language servers on first start. The current managed set is `bashls`, `clangd`, `jsonls`, `lua_ls`, `marksman`, `taplo`, `ts_ls`, and `yamlls`.

Useful Mason commands:

```vim
:Mason
:MasonLog
:checkhealth mason
```

`ts_ls` provides TypeScript and JavaScript language server support after Mason installs `typescript-language-server`.

When an LSP server is attached to the current buffer:

- `gd` go to definition
- `gD` go to declaration
- `grd` list references
- `grn` rename symbol
- `<C-Space>` trigger completion

Diagnostics:

- `g.` open diagnostic float
- `gl` send diagnostics to the location list
- `gle` display error information
- `gie` toggle inline errors
- `gve` toggle virtual line errors
- `g]` jump to next error
- `g[` jump to previous error

## Tree-sitter

Tree-sitter is managed with `nvim-treesitter` via `vim.pack`. `tree-sitter-cli` and a C compiler is required to be installed.

Useful commands:

```vim
:TSUpdate
:TSInstall lua bash json
:TSInstallInfo
:InspectTree
:checkhealth vim.treesitter
```
