The bumps are homing bars, so look for homing keys or homing bar keys.

In addition to the other responses, there are also homing scoops which I prefer but it is all preference.
Nice, I'll have to look into that!
Homing keys.
Lots of keycaps come with alternate homing keys for various layouts.
usually “homing keys” (ie. allows your fingers to find the home row)
usually custom keycap sets will have a “typist” set of some sort with extra keys in the right row profile and homing keys for at least Dvorak (but that also means buying extra keys on top of the main set)
and useless trivia – old Apple keyboards had D and K as the homing keys instead of F and J …
Learning is never useless!
ETA: I use Colemak, so I'll see if I can find something default or if I'll have to find something more piecemeal.
