title: How to create keyboard shortcuts
type: text/vnd.tiddlywiki
<<.tip """We distinguish keyboard shortcuts that work within <$macrocall $name=".tag" _="input"/> fields or <$macrocall $name=".tag" _="textareas"/> which are handled by the <$macrocall $name=".wlink" to="KeyboardWidget"/> widget and keyboard shortcuts that work globally - which means that only the page needs to have focus in order for them to be accessible - handled by a mechanism that starts to work when a wiki is loaded""">>
!!!!There's an underlying configuration mechanism that is the same for both shortcut-types:
<$vars tv-show-missing-links="no">
* (`A`) - A tiddler with the <<.def prefix>> ''$:/config/ShortcutInfo/'' + a ''unique suffix'', 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|$:/core/ui/ControlPanel/KeyboardShortcuts]] it's possible to create the ''key combination'' that should trigger the shortcut
*** Look for the ''unique suffix'' (A) and click the <$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
*** Press ''add shortcut'' if you're happy with the assigned key-combination
**** (`B`) Depending on the platform you choose the configuration mechanism creates a tiddler with a specific nomenclature:
***** $:/config/shortcuts/ + the ''unique suffix'' for shortcuts that will work on all platforms (operating systems)
***** $:/config/shortcuts-(mac/not-mac/windows/not-windows/linux/not-linux)/ + the ''unique suffix'' for shortcuts that will work on the chosen platform only or that will not work on the excluded platform
***** <$reveal state="$:/state/how-to/kb-shortcuts/platform-examples" type="nomatch" text="show"><$button class="tc-btn-invisible" set="$:/state/how-to/kb-shortcuts/platform-examples" setTo="show">Show examples</$button></$reveal><$reveal state="$:/state/how-to/kb-shortcuts/platform-examples" type="match" text="show"><$button class="tc-btn-invisible" set="$:/state/how-to/kb-shortcuts/platform-examples" setTo="hide">Hide examples</$button></$reveal><br><$reveal state="$:/state/how-to/kb-shortcuts/platform-examples" type="match" text="show" animate="yes" retain="yes">''$:/config/shortcuts/''`my-shortcut`<br>''$:/config/shortcuts-mac/''`my-shortcut`<br>''$:/config/shortcuts-windows/''`my-shortcut`<br>''$:/config/shortcuts-linux/''`my-shortcut`<br>''$:/config/shortcuts-not-mac/''`my-shortcut`<br>''$:/config/shortcuts-not-windows/''`my-shortcut`<br>''$:/config/shortcuts-not-linux/''`my-shortcut`<br></$reveal>

Keyboard shortcuts are available for common editing operations within the Text Editor:
* Confirming changes to the draft tiddler containing the keyboard focus (defaults to <kbd>ctrl-Enter</kbd>)
* Abandoning changes to the draft tiddler containing the keyboard focus (defaults to <kbd>escape</kbd>)
* Formatting operations from the tiddler editing toolbar (see the tooltips)
