Use CTRL+S to save the metadata changes.
if after save your intention is to change to another file, previous save operation is not needed. Metadata changes update is automatically done when grid active row changes.
To change to another file in the grid, without leave the InfoEdit tool, use the CTRL+Up and CTRL+Down shortcuts to move to previous or next file respectively. There is no need to click the grid to change file and get back again to the InfoEdit. These shortcuts also work in PDFView and Images view modes.
