Heya,

I added this for Epic Friday and it will be in 4.8:

Editor: Add a Control+Tab menu to quickly switch between different open assets or activate their associated tool tabs

Plus a bunch of ancillary commits to make it possible:

• https://github.com/EpicGames/UnrealEngine/commit/2a7be7f403fbacc127338083a5e33b33bba46af0
• https://github.com/EpicGames/UnrealEngine/commit/3d9b81dfa9566eb8045d8707ec4f47a376efbaa2
• https://github.com/EpicGames/UnrealEngine/commit/e1118927e3149956445dfe1cea7ddedcc4b65272
• https://github.com/EpicGames/UnrealEngine/commit/2e1a6951f40635c43494c1a27df3168be76dd92f
