less -W +F somelogfile
Using -W highlights the first (unread) new line after any forward movement such as scrolling to the next page.
Pressing SHIFT+CTRL+C (on windows) will put you back into normal mode
Pressing SHIFT+F will resume the 'tailling' (as mentioned above)

Pressing SHIFT+G will take you to the end of the file
Pressing f will forward you one page
Pressing b will take you back one page
Pressing q will quit the program
Very nifty trick!
