QuestionMark.js
When the user pushes the ? key, QuestionMark.js triggers a modal window that displays keyboard shortcuts for your app — similar to what happens on Twitter, Gmail, GitHub, etc. The modal is removed when the ESC key is pushed or the user clicks behind the modal.
I think every app that has keyboard shortcuts should do this. This could also be a generic 'help' menu for the app, but that would require some tweaking to the code and the CSS. For now, this works primarily as a shortcut keys menu.

For a demo of QuestionMark.js, go here or you can fiddle around with the version on CodePen.
Instructions
To install all the files as a dependency in your node_modules folder:
npm install question-mark-jsTo make it work, it's pretty simple. Link the CSS file in the <head> and run the script on page load (or at the bottom). Make sure all the mandatory files are included (question.mark.html, question.mark.css, and question.mark.js).
To customize, edit the question.mark.html file to include your own keyboard shortcuts. For each <ul> included with a class of help-list, a new column will be created. If you want a single column, use a single <ul>. Longer columns will scroll vertically.
Within each <ul> a single key/definition combo is inside one <li>, within which there is more markup. Edit the text to include your own app's key combos. It should be pretty self-explanatory when you look at the example markup.
Technical Info
The script is less than 1KB minified and gzip'd and it has no dependencies.
The content from question.mark.html (which also holds all the markup that builds the modal) is loaded via the Fetch API and inserted into the <body> element of the page. The modal starts out invisible and is displayed via CSS transitions.
This should work in all browsers that support the Fetch API. If you want older browser support, you'll have to use version 1.0.0, which you can get in the GitHub history.
