Help

Keyboard shortcuts are either Chords or Melodies. You can use either.

Chords are when you press many keys at once. For example Shift + f is a chord; press both Shift and f at the same time to activate the keybind (toggle fullcreen). Chords usually have a + sign between the keys.

Melodies are when keys are pressed in sequence, but not necessarily at the same time. For example, wst (widget --> stopwatch --> toggle) is a melody. Press those keys in order, and voila! The stopwatch widget will appear/disappear.

Welcome! Hi, I'm the developer of this website, Lakshya! I'd love to add your school to this website.

I'll need a few details about your school, so you can continue to the next step in either of these ways:

Use my contact form and select "I want to add my school."
Open a GitHub issue directly on this website's repository.

The GitHub repository option is preferable, because it's better for two-way communication, but feel free to do either. :]

Hope to see a message from you soon!

P.S.: If you just want to help keep your school's schedules up to date, you can still fill it out, but select something other than 'Add school' in the form or GitHub.

Hi Schedule Managers! Glad you found this page. Here are some links that you might find useful.

Links

Context Editor: Just select your school, make the necessary edits, export the file, and copy-paste it into the context.json file in the repository that you manage.

Need to migrate your version 1 context to version 2? Use the v1 to v2 context converter. Or, honestly you could just use the context editor, since it will automatically upgrade to v2 for you.

If you ever face any issues with these tools, or any issues at all, feel free to contact me (Lakshya)!

Join us :D

Want to add your school to TC22? Or maybe you just want to help keep your context up to date? You can!

Welp, I guess you found this page! It's okay, have a look around and try it out :P
