This is similar to the approach the HP-65 took, thought the '65 uses one yellow shift key for [yellow] printed Functions, and a second yellow shift for the Inverse of those same [yellow] functions.

Of course on the '59 there are actually 2 shift keys, one was simply labeled [INV], and many of these functions require pressing both [2nd] and [INV]. A less crowded looking keyboard, but more key presses to get many functions.

Trade-offs....
