a tool for precise scrolling

a tool i would find very useful is one that can perform scrolling up or down by just one pixel.  as a key association or a panel item with up and down buttons would both be usable.

somewhat often i want to compare content of different screens, either by switching user or switching workspaces.  but, too often in these cases, the common content will not line up to the same pixel.

up and down are the most needed but left and right can have their uses.  an example key binding could be Ctrl+Shift+an_arrow_key_for_direction.

Re: a tool for precise scrolling

Here is a script using xdotool:

#!/bin/bash

case $1 in
	up) 	xdotool mousemove_relative -- 0 -1 ;;
	down) 	xdotool mousemove_relative 0 1 ;;
	left) 	xdotool mousemove_relative -- -1 0 ;;
	right) 	xdotool mousemove_relative 1 0 ;;
	*) 	echo "usage: $0 [up|down|left|right]" ;;
esac

Call it using a parameter that is one of "up", "down", "left", or "right".

Assign it to launchers or keyboard shortcuts.

I assumed you meant the mouse. Can you give an example of a scrolled object scrolling by one pixel? Are you talking about a specific program?

I think Skaperen means precise drag and drop.

Re: a tool for precise scrolling

It would work in the same manner. Grab the object then use the script (or keyboard shortcuts) to move the mouse incrementally.

Re: a tool for precise scrolling

even in terminal the mouse scroll jumps one than one line unless the window is quite small.
