You can eliminate the need to manually tag by modifying your ''Create New Tiddler'' macro in your [[MainMenu]] to set the //wikiformat// field to ''t2t'':19{{{20<<newTiddler21label: "New t2t"22title: "New t2t tiddler"23fields: "wikiformat:t2t"24prompt: "Create a new tiddler using the t2t formatter">>25}}}26You should also get into [[AdvancedOptions]] or //backstage -> Tweaks -> chkInsertTabs// because that lets you hit the tab button in the tiddly text field. Tab will still move your cursor around the page, from title input to tiddly text input, etc. It only effects the text field.
