TagService was designed to save time when coding HTML. TagService will HTML tag the selected text. To determine what kind of tag to use the service searches for a colon – text before the colon is used as the Tag-Text.
Downloaded this little freebie and treid it out in Tex-Edit Plus. I had to log out to activate the Service. Then instead of doing its thing the window zoomed to full size. I soon tracked that down though: I had an Applescript set with that key command for window zooming. That must be a default as I don’t ever want to zoom a TE+ window to full screen. Once I’d ironed out those glitches it worked just fine.
Now, does it work in Safari? And the answer’s No – the key command shows and hides the Address Bar. Darn!
