When placing markups, your cursor seems to stick to certain points on the document.
The Snap function is enabled. Snap makes it easier to accurately place your markups by “snapping” your cursor to PDF content or other markups. You can find the buttons to enable and disable Snap options on the View menu and the Status Bar. Each button is highlighted in blue when active. Press the F8 key to display the Status Bar if it isn’t currently displayed.
Six buttons in the Status Bar allow you to quickly toggle these settings. While Show Grid, Reuse, and Sync don’t have snap functionality, they relate to markup placement.
Show Grid (Shift+F9): This feature displays grid points on the PDF page.
Snap to Grid (Ctrl+Shift+F9): The cursor snaps to the nearest grid point, even when the grid isn’t displayed.
Snap to Content (Ctrl+Shift+F8): The cursor snaps to the underlying content of the PDF. A small, blue square cursor will display when it’s near a grid point that it will snap to. A white square will display when the cursor is near an object that it will snap to.
Snap to Markup (Ctrl+Shift+F7): The cursor snaps to other markups on the PDF. Horizontal and vertical guidelines will also display, allowing you to snap to the horizontal or vertical location of points on other markups, even if they aren’t currently displayed. Snap to Markup is useful when creating forms, or any type of document where markups should be perfectly aligned.
Reuse Markup Tools: This feature enables the same tool to be used multiple times without having to reselect the tool on the toolbar. This mode is helpful when adding the same markup to a PDF multiple times.
Synchronize View: Synchronizes the display of multiple PDFs when viewing documents using one of the Split View modes.
Tips and keyboard shortcuts
- Snap to Content only works with vector content in the PDF. For example, the cursor will snap to lines and arcs in a PDF created from a CAD drawing. The cursor won’t snap to image content, like in a scanned PDF. Get more information here about the different types of content on a PDF.
- Snap to Content is enabled by default in the Measurement tools. To temporarily disable Snap functionality, hold down Ctrl when creating a markup.
- To snap a line to 0, 45, or 90 degrees, hold down Shift when creating a Line or Length measurement.
- You can customize the grid size and the types of points your markups will snap to. Go to Revu > Preferences (Ctrl+K), and select the Grid & Snap tab.
