Chrysler had floor button radio tuning in the mid ‘70’s (I believe) and maybe even earlier, on pre-ETR (Electronically Tuned Radios). It was not uncommon to see two “dimmer switches” on the floor of some C-bodies.
Side note: I have seen more than one person take the dimmer switch, modify it a tad and use it for a “momentary Nitrous button” (instead of for headlights). I would think a person would want a master “on/off” switch somewhere for otherwise that could lead to an unintentional problem if you put your foot down on wrong spot at wrong time - but what would I know. I've never ran Nitrous before.
@Trey, is that radio for sale?

They worked. The “pre-ETR” radios only jumped between your “preset” stations. The “ETR” would just search for a signal of a station of a certain strength (or higher).My dad had a '55 DeSoto that he bought in '57 (IIRC) and I remember him saying it had a search tune radio with the extra "dimmer switch" on the floor. Sounds like they sort of worked but not that good.
