Allow Alteryx keyboard shortcuts to be reassigned

[schaferc]

Issue

Users are not able to change keyboard shortcuts. Because some Windows keys take precedent, the Alteryx keyboard shortcut will not work. 

For example, I would like speed up performance by selecting Disable Auto Configure in User Settings, and rely on using manual canvas refreshes (F5). However, Windows is reserving F5 for the Snippet tool. As such, F5 does not work for me. And in this case, there is no button or drop down for manual refreshes. Corporate IT security prevents me from remapping my keys. 

Proposal

In user settings, allow a user to modify the full list of keyboard shortcuts.
