You move guide lines primarily by using your mouse or input device to drag them.
Moving a Single Guide Line
To adjust the position of an individual ruler guide, the method is straightforward:
- Simply position your cursor over the guide line you wish to move.
- Once the cursor changes (often indicating a move or selection tool), click and drag it to its new desired location within the document window.
- Release the mouse button when the guide is in place.
According to the reference, the fundamental action is to drag it.
Moving Multiple Guide Lines Simultaneously
If you need to reposition several guide lines at once, you can do so by selecting them before dragging:
- Shift-select the guides you want to move. This typically involves holding down the Shift key on your keyboard while clicking on each guide line you wish to include in the selection.
- After selecting the desired guides, drag them together to the new location.
- Release the mouse button and the Shift key.
The reference explicitly states: "To move multiple ruler guides, shift-select the guides you want to move, and then drag them."
This simple drag action, either individually or after shift-selecting multiple guides, is the core method for moving guide lines within your workspace.
