Is there a hotkey/shortcut for Print to Web Receipts folder?
Create a very basic Automator Service Applescript with GUI Scripting. Then, use the Keyboard Shortcuts in System Prefs to assign a shortcut.


Open Automator and Choose 'Service'
Past this script in a 'Run Applescript' Action.

tell application "System Events"
    get system attribute "sysv"
    if result is greater than or equal to 4144 then -- Mac OS X 10.3.0
        if UI elements enabled then
            tell application "Safari" to activate
            keystroke "p" using command down
            tell application process "Safari"
                tell application "System Events"
                    tell process "Safari"
                        click menu button "PDF" of sheet 1 of window 1
                        delay 1

                        click menu item "Save PDF to Web Receipts Folder" of menu of menu button "PDF" of sheet 1 of window 1
                    end tell
                end tell
            end tell
        else
            beep
            display dialog "GUI Scripting is not enabled" &amp; return &amp; return &amp; "Open System Preferences and check Enable Access for Assistive Devices in the Accessibility (or Universal Access) preference pane, then run this script again." with icon stop
            if button returned of result is "OK" then
                tell application "System Preferences"
                    activate
                    set current pane to pane "com.apple.preference.universalaccess"
                end tell
            end if
        end if
    else
        beep
        display dialog "This computer cannot run this script" &amp; return &amp; return &amp; "The script uses GUI Scripting technology, which requires an upgrade to Mac OS X 10.3 Panther or newer." with icon caution buttons {"Quit"} default button "Quit"
    end if
end tell

Set input to 'no input' and Application to 'Safari.app'
Save the Automator Service.
While still in Automator (or any app) go to the app's 'Services' menu and choose 'Services Preferences'.
Scroll rich down until you see your new service.
Assign the shortcut, click ok and your done.
