Note mouseover macros work if you use a mouse, however you can only use /ac "Physick" <mo>, adding a <t> line will give the same issue.

You could also try something like:

/ac "Physick" <tt>
/ac "Physick" <tt>
/ac "Physick" <tt>
/ac "Physick" <tt>
/ac "Physick" <tt>
/ac "Physick" <tt>
/ac "Physick" <tt>
/ac "Physick" <tt>
/ac "Physick" <t>

so if it skips a few lines due to pressing it too early, it'll still catch a <tt> around line 3-4. Can't guarantee that actually works but worth a shot.
