I had been working on setting up shortcuts on a previous release of 2.8 (blender-2.80.0-git.6fd11a21f5c5-windows64) and had set up many including move, rotate, scale and countless others. Although my keymap prefs live under appdata>roaming>Blender Foundation>Config>Scripts>presets>keyconfig, after I downloaded the latest version of Blender (blender-2.80.0-git.99d4321feff6-windows64) almost all my custom keymaps became inert :-/ I had saved out my keymap file in anticipation of such a thing, yet even when I went ahead and reimported them back in in the aforementioned release of 2.8, Blender refuses to recognize it. But when I switch back to the previous version, the keymap file is recognized just fine.
Here is the keymap file that I saved out:W is for move, E is for Rotate, E is for scale and Q is for rectangle select (to name a few major ones)
