Hello all,

This is the cursor that appears when you want to change the column width in Excel using the mouse. It's the one that looks like a vertical line with an outwards-pointing arrowhead on each side (or like a cross with arrowheads on the two side arms. I hope that helps - it's really difficult to describe! Does anyone know what it's called in English?

Thanks a lot!
