lever (n.)
c. 1300, from Old French levier (Modern French leveur) "a lifter, a lever," agent noun from lever "to raise," from Latin levare "to raise," from levis "light" in weight, from PIE root *legwh- "light, having little weight; easy, agile, nimble" (cognates: Sanskrit laghuh "quick, small;" Greek elakhys "small," elaphros "light;" Old Church Slavonic liguku, Lithuanian lengvas "light;" Old Irish laigiu "smaller, worse;" Gothic leihts, Old English leoht "light" (adj.)). As a verb, 1856, from the noun.
1. We can see that it looks like a button, but how do we know what it will accomplish when we press it? Unlike mechanical objects, you can’t figure out a virtual lever’s function just by tracing its connections to other mechanisms—software can’t be casually inspected in this manner.
