One of the major advantages to using Inkscape over Adobe Reader for projecting patterns, is that Inkscape has infinite scrolling in all directions, so we never run out of scrolling room.
(“Running out of scrolling room” creates problems for projecting because it limits where we can move the PDF around the screen and get pieces to be projected where we need them on our screen. With Inkscape’s infinite scrolling, we don’t have that problem and no longer have to add large margins to our patterns as a workaround.)
To use the keyboard to move the pattern when projecting or the calibration tool when calibrating press the Control key (Command key on a Mac) and the arrow key.
Pressing only the arrow key will not work, Control/Command at the same time as the arrow key will do the micro-scrolling we need.
