Non obvious features

1. Inserting media in HTML strings: To insert media, other than using media manager, one can type <path>filename</path>. For example, <img src='<path>blue.png</path>'></img> will show an image file on page.

2. Set a list of keyboard responses (e.g., in the image-keyboard-response plugin): To set which keys should be listened to, one can input a character sequence. Anything wrapped in {} is considered one key. For example, {enter}ABC will use the keys ENTER, A, B, and C.
