Command(s) to review all the HL in a room while we were away
People (like me) sometime go away from their computer for a long time (week-end), and when they come back, they review all the places where they have been highlighted.
A command to ease this process could be useful.
For example (when the feature 1487 is implemented):
Ctrl+G (or something else) :
If you're at the bottom of the window, scroll up to the bar (to the last line we saw).
Doing Ctrl+G again will scroll down to the next highlight in this window, again and again, until the end of the conversation.
The highlight should be centered in the window when doing this.
