Minor correction, for Advanced Shortcut keys, it's "k" for the GM layer. While "o" for objects, and "m" for maps are a nice mnemonic, "k" and "," were likely chosen for their positions on the keyboard, between "o" and "k" and adjacent to "m" and "k" respectively. For mnemonics, you could use "k"eep away from players, and the "," looks kind of like a torch. =D TheMarkus1204 said: But normally you select the layer just once and if you do so, you do not use any Macros or do you? Besides, there are shortcuts (although some are not very intuitive) to switch layers: "o" for Token Layer (I can understand why they did this, "o" = Object), but still "t" would be better IMO!) "g" for GM Layer "," for Lighting Layer (WHY "," instead of "l" or something alike?) "m" for map Layer
