How many places in the game is this actually used? The only ones I can think of are the lever that Thrundarr stands on, and then the two levers in D50. (It is, of course, entirely possible that I am forgetting some.) If these are the only two places where it's used, could it be renamed to "pull lever" or something similar? Or could it even be merged into the Use command, giving a "do you want to pull the lever/handle the object/whatever?" option if you use that command in a context-sensitive space?

The "h"andle command has been expanded to a generic "handle dungeon feature" command, so it's not just levers anymore.

I would deprecate that command and make use of 'u'se one which could simply prompt if you're standing on the dungeon feature if the one would like to use it. 'h'andle can be left for old folks.

But if not... In other roguelikes such command is also called 'I'nteract (with environment) or e'x'amine (environment).

Fixed. By renaming the command help text to "Handle something" and the quick hint to "Handle environmental feature". We'll test this.
