- * The event may be a mouse event (click, double-click, middle-click) or keypress event (enter).
- *
- * On Windows, the modifiers are:
- * Ctrl new tab, selected
- * Shift new window
- * Ctrl+Shift new tab, in background
- * Alt save
- *
- * You can swap Ctrl and Ctrl+shift by toggling the hidden pref
- * browser.tabs.loadBookmarksInBackground (not browser.tabs.loadInBackground, which
- * is for content area links).
- *
- * Middle-clicking is the same as Ctrl+clicking (it opens a new tab) and it is
- * subject to the shift modifier and pref in the same way.
- *
- * Exceptions:
- * - Alt is ignored for menu items selected using the keyboard so you don't accidentally save stuff.
- * (Currently, the Alt isn't sent here at all for menu items, but that will change in bug 126189.)
- * - Alt is hard to use in context menus, because pressing Alt closes the menu.
- * - Alt can't be used on the bookmarks toolbar because Alt is used for "treat this as something draggable".
- * - The button is ignored for the middle-click-paste-URL feature, since it's always a middle-click.
