# Commands

You can control SumatraPDF with commands:

- use [command palette](Command-Palette.md) (`Ctrl + K`) to invoke a command by its description
- [customize a keyboard shortcut](Customizing-keyboard-shortcuts.md) to invoke a command by its id
- **ver 3.5+:** [send a command via DDE](DDE-Commands.md) e.g. `[CmdClose]` to invoke `Close Document` command
- **ver 3.6+:** some commands [accept arguments](Commands.md#commands-with-arguments)

# Commands with arguments

**Ver 3.6+:** some commands accept arguments which provides more capabilities when creating [custom keyboard shortcut](Customizing-keyboard-shortcuts.md).

For example:

```
Shortcuts [
    [
        Cmd = CmdCreateAnnotHighlight #00ff00 openedit
        Key = a
    ]
]
```

By default `a` invokes `CmdCreateAnnotHighlight` with default yellow color.

You can over-ride `a` shortcut to create green (`#00ff00`) highlight annotation instead and automatically open annotations edit window (`openedit` boolean argument).

You can create multiple keyboard shortcuts for multiple colors.

Arguments can be: strings, numbers, booleans, colors (`#rrggbb` or `#aarrggbb` format).

Arguments have names. For example `CmdCreateAnnotHighlight` has `color` argument of type color and optional `openedit` boolean argument.

The format of providing arguments is: `CmdCreateAnnotHighlight color: #fafafa openedit: true`.

For boolean arguments name is the same as `true` value i.e. `openedit` is the same as `openedit: true`.

For default arguments you can skip the name. For example: `color` is a default `CmdCreateAnnotHighlight` argument so `CmdCreateAnnotHighlight #fafafa` is the same as `CmdCreateAnnotHighlight color: #fafafa`

You can combine those rules: `CmdCreateAnnotHighlight #fafafa openedit` is the same as `CmdCreateAnnotHighlight color: #fafafa openedit: true`.

## `CmdScrollUp`, `CmdScrollDown`

**Ver 3.6+**

Arguments:

- `n` : default, integer, how many lines to scroll up or down (default: 1)

Use case: if you want to speed up scrolling with `j`, `k` keys, you can re-assign them:

```
Shortcuts [
    [
        Cmd = CmdScrollDown 5
        Key = j
    ]
    [
        Cmd = CmdScrollUp n: 5
        Key = k
    ]
]
```

## `CmdGoToNextPage`, `CmdGoToPrevPage`

**Ver 3.6+**

Arguments:

- `n` : default, integer, how many pages to advance by (default: 1)

Use case: if you want to go forward, back by more than 1 page

## `CmdCreateAnnotHighlight` and other `CmdCreateAnnot*`

Arguments:

- `color` : default, color
- `openedit` : boolean, `false` if not given
- `copytoclipboard` : boolean, `false` if not given. For highlight/underline/squiggly/strikeout annotations, copies the selection (text of annotation) to clipboard. This used to be default behavior for built-in `a` etc. keyboard shortcuts but now it has to be explicitly chosen.
- `setcontent` : boolean, false if not given. For highlight/underline/squiggly/strikeout sets content of annotation to the selection (text of annotation)

Use cases:

- change default color for annotations
- create multiple shortcuts for different colors

Example: change `a` to create green highlight annotation:

```
Shortcuts [
    [
        Cmd = CmdCreateAnnotHighlight #00ff00 openedit
        Key = a
    ]
]
```

## Other CmdCreateAnnot\* arguments

**Ver 3.6+**

Arguments for `CmdCreateAnnotHighlight` plus:

- `color` : default, color of text and border, black if not given
- `bgcolor` : background color of annotation, fully transparent if not given
- `textsize` : size of annotation text, 12 if not given
- `borderwidth` : border width, 1 if not given
- `opacity` : opacity of annotation, 0 - fully transparent (i.e. invisible), 100 - fully opaque (default if not given)
- `interiorcolor` : interior color for circle, square etc. annotations, fully transparent if not given
- `focusedit` : boolean, when annotation edit window opens, focus the contents edit control
- `focuslist` : boolean, when annotation edit window opens, focus the annotations list

## `CmdZoomCustom`

**Ver 3.6+**

Arguments:

- `level` : default, string or integer, zoom level

`level` can be:

- a number describing zoom level in percent e.g.:
  - `50` or `50%` means 50% zoom
  - `125` means 125% zoom
- a virtual zoom level:
  - `actual size` (100% zoom level)
  - `fit page`
  - `fit width`
  - `fit content`

Example:

```
Shortcuts [
    [
        Cmd = CmdZoomCustom 50%
        Key = z
    ]
]
```

## `CmdCommandPalette`

**Ver 3.6+**

Argument:

- `mode` : default, optional string, Values:
  - `@` for opened files (tabs)
  - `#` for history of files
  - `>` for commands

Without an argument it defaults to `>`.

Example:

```
Shortcuts [
    [
        Cmd = CmdCommandPalette #
        Key = Ctrl + h
    ]
]
```

# Debugging

If a custom shortcut defined in `Shortcuts` doesn't work it could be caused by invalid command name or invalid command arguments.

We log information about unsuccessful parsing of a shortcut so [check the logs](Debugging-Sumatra.md#getting-logs) if things don't work as expected.
