Customize project context menu of visual studio

You can always use the keyboard to do the work for you.

• The default binding for Properties is Alt+Enter (or sometimes F4 depending on what add-ins you have installed). Select the project in Solution Explorer and hit Alt+Enter to show it's properties. (This works for almost any other object as well, btw).
• The default binding for view SolutionExplorer is Ctrl+Alt+L, so you don't have to use your mouse to get there.
• There is no default binding for opening a project in Windows Explorer, but you can set one yourself.

The keyboard bindings are set under Tools->Options...->Environment->Keyboard, and the interesting settings in this case are probably View.SolutionExplorer, Project.OpenFolderinWindowsExplorer and View.PropertiesWindow or Project.Properties depending on which propertiy collection you were referring to.

Yes, it can be edited.

• Go to 'Tools' -> 'Customize...' -> and select the 'Command' tab.
• Select Context Menu and pick Project and Solution Context Menus | Project
