If you just start typing when a browse list is active, the software will assume you want to locate to something. The appropriate locator will pop-up with the keys you typed pre-loaded, just as if you’d pressed the locator button first.
The same selection mechanism is used for locating, as described in Locating by selecting, when you press the ellipsis buttons on forms. You can exploit this to ‘drill-down’ to detail from almost anywhere. Pressing a locator or an ellipsis will typically bring up a selection list. From there you can press Detail to show the associated form, and then press another ellipsis on that to go deeper, and so on.
