There are two related questions about resetting VisualStudio keyboard scheme and importing VisualStudio settings. However, this doesn\'t seem to play nice all together.
You can call devenv.exe directly and pass the /ResetSettings switch. Here is a link to the command line options for Visual Studio: https://msdn.microsoft.com/en-us/library/xee0c8y7.aspx
You can execute devenv.exe using the Systems.Diagnostics.Process class to reset the settings:
Devenv.exe /ResetSettings
You can, optionally, pass a settings file which contains the settings you want to restore:
Devenv.exe /ResetSettings "C:\My Files\MySettings.vssettings"
In Visual Studio, you can export selected settings by going to Tools > Import and Export Settings... and selecting "Export Selected Environment Settings". Then, only choose the Keyboard checkbox under the All Settings > Options > Environment subtree.
