[SOLVED] Xterm: using a mouse with the scrollbar

I would like to be able to move the scrollbar position in Xterm by left clicking on (or above or below) it. The Arch Wiki (https://wiki.archlinux.org/index.php/Xterm#Scrollbar) says that this is how it should work, but when I left click anywhere on the scrollbar it only changes the mouse cursor to an up arrow; the text does not scroll regardless of the position of the scrollbar. BUT, upon highlighting the text after having tried to scroll, I can see that the text did in fact scroll, but the screen is not refreshing for some reason.

.Xresources (I do run xrdb after each change):

URxvt.font: xft:Commodore 64 Rounded:size=12
URxvt.letterSpace: -2 

URxvt.internalBorder: 10px

URxvt.foreground:	#00ffff
URxvt.background:	#000000

URxvt.scrollBar:     false 

URxvt.perl-ext-common: default,tabbed
URxvt.tabbed.tabbar-fg:15 
URxvt.tabbed.tabbar-bg: 0
URxvt.tabbed.tab-bg: 15


XTerm.vt100.scrollBar: true
XTerm..scrollbar.width: 20
XTerm..saveLines: 4096

Re: [SOLVED] Xterm: using a mouse with the scrollbar

This is explained in the xterm manpage.
Add

*VT100.scrollbar.translations:  #override \n\
    <Btn5Down>:     StartScroll(Forward) \n\
    <Btn1Down>:     StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
    <Btn4Down>:     StartScroll(Backward) \n\
    <Btn1Motion>:   MoveThumb() NotifyThumb() \n\
    <BtnUp>:        NotifyScroll(Proportional) EndScroll()

to your resources. (Straight copy from the manpage)

Thank you. This solved it. I tried the other example and found that both didn't quite do what I wanted but found that things worked a little better as:

*VT100.scrollbar.translations:  #override \n\
              <Btn1Down>:     StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
              <Btn1Motion>:   MoveThumb() NotifyThumb() \n\
              <BtnUp>:        NotifyScroll(Proportional) EndScroll()

The above code allows for both left handed grabbing and mouse wheel up/down and little to no tearing.
