How to access the activeTiddler as a variable

[arunnbabu81]

Is there any variable available to access the activeTiddler. I have some keyboard shortcuts which work on the current active tiddler in the historylist $:/HistoryList!!current-tiddler . Keyboard shortcut code is like this

<$action-setfield $tiddler={{$:/HistoryList!!current-tiddler}}  tiddler-multicolumn-view="1-column" column-1="$:/arsheth/tiddler-multicolumn-views/codeblock-template" />

Instead of $tiddler={{$:/HistoryList!!current-tiddler}} I want to use the activeTiddler as defined in your plug in. Is that available as a variable like currentTiddler
