Windows – Shortcut to open Network Connections from Run

ncpa.cpl will open up the Network Connections window.

Or you can create a Shortcut to:
C:\Windows\System32\control.exe ncpa.cpl

Official MS List of .cpl commands to access a number of Control Panel tools.

I know it's been a year since you asked this, but ...

You can open the Quick Switch Project dialog using ctrl+alt+p (this actually this runs the prompt_select_workspace command). Selecting a Project form the dialog will close your current project and replace it with the selected project. While that has its uses, I wanted to actually open multiple recent projects at the same time.

What I ended up doing was mapping ctrl+super+p 1 to open the recent project, ctrl+super+p 2 for the next most recent, and so on for the top 5. So, to open the most recent project, I hit ctrl+super+p then hit 1.

I did this by adding keymappings to the the Default keymap for User. To do this yourself, from the main menu, select "Preferences" -> "Key Bindings". Sublime will open 2 files: "Default" (on the left) and "User" (on the right). Add the following to the "User" file:

{ "keys": ["ctrl+super+p", "1"], "command": "open_recent_project_or_workspace", "args": {"index" : 0} },
{ "keys": ["ctrl+super+p", "2"], "command": "open_recent_project_or_workspace", "args": {"index" : 1} },
{ "keys": ["ctrl+super+p", "3"], "command": "open_recent_project_or_workspace", "args": {"index" : 2} },
{ "keys": ["ctrl+super+p", "4"], "command": "open_recent_project_or_workspace", "args": {"index" : 3} },
{ "keys": ["ctrl+super+p", "5"], "command": "open_recent_project_or_workspace", "args": {"index" : 4} },

It should look something like this:

You could map something like crtl+super+o 1 to open the most recent file (I use crtl+shitft+t to undo the last closed file ...a lot). To that same "User" file, add:

{ "keys": ["ctrl+super+o", "1"], "command": "open_recent_file", "args": {"index" : 0} },
{ "keys": ["ctrl+super+o", "2"], "command": "open_recent_file", "args": {"index" : 1} },
{ "keys": ["ctrl+super+o", "3"], "command": "open_recent_file", "args": {"index" : 2} },
{ "keys": ["ctrl+super+o", "4"], "command": "open_recent_file", "args": {"index" : 3} },
{ "keys": ["ctrl+super+o", "5"], "command": "open_recent_file", "args": {"index" : 4} },

Hope this helps!
