`gg`	First row
`G`	Last row
`0`	First column
`$`	Last column
`Ctrl-D` / `Ctrl-U`	Half-page down/up
`Ctrl-F` / `Ctrl-B`	Full page down/up
`w` / `b`	Next/previous non-empty cell
`i` / `a` / `Enter`	Edit cell (Insert mode)
`x`	Clear cell
`dd`	Delete row
`yy`	Yank row
`p` / `P`	Paste below/above
`u`	Undo
`Ctrl-R`	Redo
`v`	Visual selection
`Ctrl-V`	Visual block selection
`/`	Search
`n` / `N`	Next/previous match
`:`	Command mode

Insert Mode

Type to edit the cell. ESC or Enter confirms.

Visual Mode

Select with hjkl, then y to yank, d to delete.

Commands

Command	Action
`:w`	Save
`:w file.csv`	Save as CSV
`:w file.cell`	Save as native format
`:w!`	Force save (flatten formulas)
`:q`	Quit
`:q!`	Quit without saving
`:wq`	Save and quit
`:e file`	Open file
`:sort A asc`	Sort by column A ascending
`:sort B desc`	Sort by column B descending

Formulas

Formulas start with = and support Excel-compatible syntax:

=A1+B1
=SUM(A1:A10)
=AVERAGE(B1:B5)
=IF(A1>100, "high", "low")

Supported Functions (v1)

SUM, AVERAGE, COUNT, MIN, MAX, IF

Formula compliance with the ODF (OpenDocument Formula) spec is tracked and will expand over time.

File Formats

CSV/TSV -- Opens and saves standard comma/tab-separated files. Formulas are flattened to their computed values on CSV export.
**.cell** -- Native format that preserves formulas. Plain text, human-readable, inspired by sc-im.

When saving a CSV that contains formulas, cell warns you and suggests saving as .cell instead. Use :w! to force a CSV save.

Architecture

cell/
  crates/
    cell-sheet-core/    # Data model, formula engine, file I/O (no TUI dependency)
    cell-sheet-tui/     # Ratatui rendering, Vim modes, event loop

The core library is independent of the terminal UI and can be tested without a terminal.

Releasing

Update the version in [Cargo.toml](Cargo.toml) (workspace version)
Update [CHANGELOG.md](CHANGELOG.md) with the new version's changes
Commit: git commit -am "release: bump to vX.Y.Z"
Tag and push:

 git tag vX.Y.Z
 git push origin main --tags

Pushing a v* tag triggers the release workflow, which:

Builds binaries for Linux (x86_64, aarch64), macOS (x86_64, aarch64), and Windows (x86_64)
Creates a GitHub Release with the binaries attached
Publishes cell-sheet-core and cell-sheet-tui to crates.io via trusted publishing
