###About: This script adds buttons and keyboard shortcuts that make it easy to add/remove:

• <kbd> tags
• Superscripts and subscripts
• <del> tags
• <br> tags
•  

when editing posts.

###Old Screenshot ^{_{(Last 3 tags not shown)}}:

###To use:

Click the button or press AltK on the keyboard and <kbd></kbd> will be inserted at the cursor.
If text is selected, it will be wrapped by the <kbd> tags instead.

Likewise for the Superscript and Subscript tags, the keyboard shortcuts are Alt↑ and Alt↓ (Up arrow and Down arrow).

The delete (semantic strikethrough) shortcut is AltX.
While breaks (<br>) are inserted via click or the AltB shortcut.
And  s use AltM.

Tags are wrapped and unwrapped the same way that other markup (Bold, Italic, etc.) is -- including how whitespace and nested tags are handled.

Update: <kbd> now wraps in word mode. So Ctrl P becomes <kbd>Ctrl</kbd> <kbd>P</kbd>, etc.
All other tags wrap normally ^{_{(unless they don't have an end tag)}}.
