title: How to create keyboard shortcuts

<<.tip """We distinguish keyboard shortcuts that work within <$macrocall $name=".tag" _="input"/> fields or <$macrocall $name=".tag" _="textareas"/> which are handled by the <$macrocall $name=".wlink" to="KeyboardWidget"/> widget and keyboard shortcuts that work globally - which means that only the page needs to have focus in order for them to be accessible - handled by a mechanism that starts to work when a wiki is loaded""">>

!! The configuration mechanism is the same for both shortcut-types
|
|
|
|
<$vars tv-show-missing-links="no">
|
|
|
|
A tiddler with the <<.def prefix>> `$:/config/ShortcutInfo/` and a ''unique suffix'' appended, like `my-shortcut`, makes the new shortcut appear in the $:/ControlPanel within the [[Keyboard Shortcuts Tab|$:/core/ui/ControlPanel/KeyboardShortcuts]]. An optional description can be added within its text field
|
|
|
|
In the [[Keyboard Shortcuts Tab|$:/core/ui/ControlPanel/KeyboardShortcuts]] the ''key combination'' that should trigger the shortcut can be configured:
|
|
|
|
> Look for the ''unique suffix'' defined for the new shortcut and click the <$button class="tc-btn-invisible">{{$:/core/images/edit-button}}<$action-sendmessage $message="tm-notify" $param="$:/core/images/edit-button"/></$button> button to open a popup that detects ''key combinations'' and shows the detected combination in its input field
|
|
|
|
>The ''add shortcut'' assigns the key-combination to the shortcut
|
|
|
|
Depending on the chosen platform the configuration mechanism creates a tiddler with a specific nomenclature
|
|
|
|
> $:/config/shortcuts/ + the ''shortcut suffix'' for shortcuts that will work on all platforms (operating systems)
|
|
|
|
> $:/config/shortcuts-(mac/not-mac/windows/not-windows/linux/not-linux)/ + the ''shortcut suffix'' for shortcuts that will work on the chosen platform only or that will not work on the excluded platform
|
|
|
|
Examples
|
|
|
|
* $:/config/shortcuts/`my-shortcut`
|
|
* $:/config/shortcuts-mac/`my-shortcut`
|
|
* $:/config/shortcuts-windows/`my-shortcut`
|
|
* $:/config/shortcuts-linux/`my-shortcut`
|
|
* $:/config/shortcuts-not-mac/`my-shortcut`
|
|
* $:/config/shortcuts-not-windows/`my-shortcut`
|
|
* $:/config/shortcuts-not-linux/`my-shortcut`

<<.tip """Note that you don't have to create those platform-specific tiddlers manually if you simply create the ''ShortcutInfo'' tiddler as mentioned above and configure the shortcut in the ~ControlPanel""">>

<br>
|
|
|
|
!! At this point the shortcut is defined and its ''actions'' can be configured
|
|
|
|
!! Using the [[Keyboard Widget|KeyboardWidget]]
|
|
|
|
> A <<.wlink "KeyboardWidget">> widget detects the key combinations pressed within an <<.tag input>> or <<.tag textarea>> field within its scope. The <<.wlink "KeyboardWidget">> widget needs to "embrace" the <<.tag input>> or <<.tag textarea>> field and its <<.attr key>> attribute either points to a configuration tiddler using the [[Key Descriptor]] Syntax or explicitely contains the key
|
|
|
|
```
|
|
<$keyboard key="((my-shortcut))" actions='<$action-setfield $tiddler="my-tiddler" $field="my-field" $value="my-value"/>'>
|
|
|
|
<$edit-text tag="input" tiddler="my-tiddler"/>
|
|
|
|
</$keyboard>
|
|
```
|
|
|
|
```
|
|
<$keyboard key="alt-shift-M" actions='<$action-setfield $tiddler="my-tiddler" $field="my-field" $value="my-value"/>'>
|
|
|
|
<$edit-text tag="input" tiddler="my-tiddler"/>
|
|
|
|
</$keyboard>
|
|
```
|
|
|
|
> If actions are defined , the <<.wlink KeyboardWidget>> widget will invoke the actions defined in its <<.attr actions>> attribute when it detects the key-combination defined in its <<.attr key>> attribute being pressed in any <<.tag input>> or <<.tag textarea>> field within its scope
|
|
|
|
<br>
|
|
|
|
!! Using global Keyboard Shortcuts
|
|
|
|
> The actions for ''global'' keyboard shortcuts are stored in the ''text'' field of tiddlers tagged with <<tag $:/tags/KeyboardShortcut>>
|
|
|
|
> The ''key field'' connects an action-tiddler with the corresponding shortcut through the `((my-shortcut))` syntax, called [[Keyboard Shortcut Descriptor]]
|
|
|
|
:<h3> Syntax: `((` + `a chosen suffix` + `))` </h3>
|
|
|
|
> If the tiddler has the tag <<tag $:/tags/KeyboardShortcut>>, the field ''key'' with the [[Keyboard Shortcut Descriptor]] as its value and some actions in its text field, the actions will be triggered when the mechanism detects the configured key-combination
|
|
|

<$macrocall $name=".tip" _="""''Macros'' defined ''outside'' a global keyboard-shortcut (through a tiddler tagged `$:/tags/Macro`) need to be ''imported'' in order to be accessible.
