PubMed Results Action Bar has been redesigned

PubMed users will want to take note that as of today, March 28, 2005, the results action bar has been redesigned so selections from the Display format, Show, Sort by, or Send to menus (text, file, clipboard and e-mail) take effect automatically.

""In the past, after making selections from the pull-down menus, it was necessary to then click on the Display or Send to buttons. Many users were confused by that step, so the Action bar will change to pull-down menus that do not require buttons (see Figure 1). As soon as you select an option from a menu you will notice an immediate change as PubMed follows that instruction. You may find some selections take a moment to complete, e.g., sorting a large set. PubMed's paging feature that allows you to enter the number of the page you want to display will continue to use a button."
