At the moment the script is specialised for the phpbb forum, but it can be adjusted for any other forum.
Due to using RegEx inside the script, your version of Autohotkey has to be 1.0.46+ when you want to use the source files.

If you have created a language file on your own, feel free to share it with the community. I'll add it to a future release if you're interested.

Tag compose mode:
Some words about the new compose mode. Imagine you want to apply more than one tag at once - make use of the Ctrl key.
E.g. you want a word bold and italic formatted. Highlight the word, press Ctrl, press the bold button, release the Ctrl key and press italic button. Voilа. This also works without highlighting a word. In this case the caret is moved inside the tags to start writing.

As long as you hold the ctrl key, the tags are copied to clipboard. The first button press without holding the Ctrl key will paste the collected tags.
