And make a shortcut myself, second one was copied from the site, it worked when I typing in the input widget, but the first one not worked, I don’t know why seems no difference.
! not worked
<$keyboard key="alt-shift-k" actions='<$action-sendmessage $message="tm-edit-text-operation" $param="wrap-selection" prefix="<<ML " suffix=">>"/>'>
<$edit-text tag="input" tiddler="my-tiddler"/>
</$keyboard>
! worked
<$keyboard key="alt-m" actions='<$action-setfield $tiddler="my-tiddler" $field="my-field" $value="my-value"/>'>
<$edit-text tag="input" tiddler="my-tiddler"/>
</$keyboard>
If I change <$edit-text tag="input" tiddler="my-tiddler"/> to <$edit-text tag="textarea" tiddler="my-tiddler"/> is not worked too.
I had a similar question elsewhere before, so while I remember, if those actions were somehow enhanced to work with a user generated edit-text widget in addition to “the editor” that would be a MASSIVE win for a new generation of editing and content creating enhancements!!
