# Command Mode
You enter command mode by typing `:` while in navigation mode. You can then
type a command and hit `Enter` to execute it or `Esc` to cancel.
The currently supported commands are:
* `write [path]` save the current spreadsheet. If the path is provided it will save it to that path. If omitted it will save to the path you are currently editing. `w` is a shorthand alias for this command.
* `insert-rows [number]` Inserts a row into the sheet at your current row. If the number is provided then inserts that many rows. If omitted then just inserts one.
* `insert-cols [number]` Just line `insert-rows` but for columns.
* `rename-sheet [idx] <name>` rename a sheet. If the idx is provide then renames that sheet. If omitted then it renames the current sheet.
* `new-sheet [name]` Creates a new sheet. If the name is provided then uses that. If omitted then uses a default sheet name.
* `select-sheet <name>` Select a sheet by name.
* `edit <path>` Edit a new spreadsheet at the current path. `e` is a shorthand alias for this command.
* `quit` Quits the application. `q` is a shorthand alias for this command.
<aside>Note that in the case of `quit` and `edit` that we do not currently
prompt you if the current spreadsheet has not been saved yet. So your changes
will be discarded if you have not saved first.</aside>

# Edit Mode
You enter Edit mode by hitting `e` or `i` while in navigation mode. Type
what you want into the cell.
Starting with:
* `=` will treat what you type as a formula.
* `$` will treat it as us currency.
Typing a number will treat the contents as a number. While typing non-numeric
text will treat it as text content.
<aside>We do not yet support modifying the type of a cell after the fact. We
may add this in the future.</aside>
For the most part this should work the same way you expect a spreadsheet to
work.
* `Enter` will update the cell contents.
* `Esc` will cancel editing the cell and leave it unedited.
* `Ctrl-p` will paste the range selection if it exists into the cell.
`Ctrl-r` will enter range select mode when editing a formula. You can navigate
around the sheet and hit space to select that cell in the sheet to set the
start of the range. Navigate some more and hit space to set the end of the
range.
You can find the functions we support documented here:

* [Visual](./visual.md)
**Cell Navigation** * [Command](./command.md)

many times. So typing `123h` will move to the left 123 times. Hitting `Esc`
will clear the numeric prefix if you want to cancel it.
**Modifying the Sheet or Cells**
* `e` or `i` will enter CellEdit mode for the current cell.

* `d` will delete the contents of the range leaving any style untouched
* `D` will delete the contents of the range including any style
When you have selected the end of the range you will exit range select mode and
the range reference will be placed into the cell contents you are editing.
<aside>We only support continuous ranges for the moment. Planned for
discontinuous ranges still needs the interaction interface to be
determined.</aside>

# Intro
## Supported formats
Currently we only support the [ironcalc](https://docs.ironcalc.com/) xlsx
features for spreadsheet. I plan to handle csv import and export at some point.
I also might support other export formats as well but for the moment just csv
and it's variants such as tsv are in the roadmap.
## User Interface
The sheetui user interface is loosely inspired by vim. It is a modal interface
that is entirely keyboard driven. At nearly any time you can type `Alt-h` to
get some context sensitive help.
## Modal Docs
To get help on each modality in command mode `:` type
* `help navigate`
* `help edit`
* `help command`
* `help visual`
