Hi John-91,
Thank you for reaching out to Microsoft Q & A forum.
"Hover" is correct in the context provided. The action described involves moving the cursor over a screen element without clicking, which is accurately conveyed by the word "hover."
So, the sentence should be:
"Hover over the title of a column and use the vertical line to resize the column."
This usage is correct and aligns with the context of the instructions given.
