If you press the keyboard combination Alt, Shift, "<" (which is common in Emacs), it sometimes happens that the Alt modifier gets stuck in the down position. A single press on Alt_L releases it again. 

If you instead press Shift, Alt, "<" (it Shift before Alt), you get a ">" symbol instead of the desired action (which is to go to the end of the document).  

In both cases, the problem seems to be caused by Alt_L in two places in the keyboard layout:

$ xmodmap -pke | grep Alt
keycode  64 = Alt_L Meta_L
keycode 204 = NoSymbol Alt_L

Removing any of them solves both problems above. Ie, it works with:

$ xmodmap -pke | grep Alt
keycode 64 = Alt_L Meta_L

but also:

$ xmodmap -pke | grep Alt
keycode 204 = Alt_L Meta_L

It could be that the code in Xvnc assumes that Alt_L can only be found in one single location in the keyboard layout.
