There are various ways of assigning a keystroke to it.
One would be to save the following code as an applescript, and assign a keystroke to the Applescript with something like FastScripts or Keyboard Maestro.
Code:
-- Copy as PDF
-- Assign to a keyboard shortcut with FastScripts or Keyboard Maestro ...
tell application id "sevs"
set mnuCopy to my GetMenuItem("OGfl", {"Edit", "Copy As", "PDF"})
tell application id "OGfl" to activate
click mnuCopy
end tell
-- RETURNS A REFERENCE TO A CLICKABLE MENU ITEM
-- E.G. set mnuZoomFit to GetMenuItem("OGfl", {"View", "Zoom", "Zoom to Selection"})
on GetMenuItem(strAppCode, lstMenu)
set lngChain to length of lstMenu
if lngChain < 2 then return missing value
tell application id "sevs"
set lstApps to application processes where its creator type = strAppCode
if length of lstApps < 1 then return missing value
tell first item of lstApps
-- GET THE TOP LEVEL MENU
set strMenu to item 1 of lstMenu
set oMenu to menu strMenu of menu bar item strMenu of menu bar 1
-- TRAVEL DOWN THROUGH ANY SUB-MENUS
repeat with i from 2 to (lngChain - 1)
set strMenu to item i of lstMenu
set oMenu to menu strMenu of menu item strMenu of oMenu
end repeat
-- AND RETURN THE FINAL MENU ITEM
return menu item (item -1 of lstMenu) of oMenu
end tell
end tell
end GetMenuItem
on GUIEnabled()
tell application id "sevs"
if UI elements enabled then
return true
else

display dialog "This script depends on enabling access for assistive devices in system preferences" buttons "OK" default button "OK" with title pTitle & " " & pVer
tell application id "sprf"
