My mother has macular degeneration and is losing her eyesight. On a regular basis, she manages to accidentally hit a random button and then cannot get her TV and/or surround receiver to work right.

I need either:

1) a big button remote, as SIMPLE as possible (few buttons as possible) that can be toggled between TV and receiver,

-OR-

2) two separate remotes, one for each.

Believe me, the simpler the better. If she accidentally pushes a wrong button, it means a trip over there to fix it!

TV is a rather common brand (I can update tomorrow when I see her).

Receiver is an Insignia (Best Buy home brand).

I will be eternally grateful if the collective wisdom can point me in the right direction!!!
