Mac Question: Anybody know how to get services or keyboard shortcuts to work in a plugin?

Sorry I may have confused.

Original post was about getting keyboard shortcuts set up for the user, and the follow-up/reply post was about issuing keystrokes programmatically.

Regarding the former, maybe univesal access is required - dont really know.

Regarding the latter, the following code is part of the framework available at https://www.assembla.com/spaces/lrdevplugin/

It allows a plugin to send keystrokes like "p" to pick a photo, or "Cmd-S" to save metadata. There is a windows counterpart as well...

--[[
        Send key string verbatim to Lightroom.
       
        Uses applescript string passed to osascript.
--]]
function Mac:sendUnmodifiedKeys( keyStr, keyDowns, keyUps )
    local scriptTbl = {}

    scriptTbl[#scriptTbl + 1] = "-e 'tell application \"Lightroom\" to activate'"
    scriptTbl[#scriptTbl + 1] = "-e 'tell application \"System Events\"'"

     if keyDowns then
        tab:appendArray( scriptTbl, keyDowns )
    end

    scriptTbl[#scriptTbl + 1] = "-e 'keystroke \"" .. keyStr .. "\"'"

    if keyUps then
        tab:appendArray( scriptTbl, keyUps )
    end

    scriptTbl[#scriptTbl + 1] = "-e 'end tell'"

    local scriptStr = table.concat( scriptTbl, ' ' )
    local command = 'osascript'
    local params = scriptStr

    return self:executeCommand( command, params ) -- no targets, no output.
end

--[[
        Send mac-modified keystroke sequence to mac os / lightroom.
       
        Format examples:
       
            Ctrl-S
            Cmd-FS
            ShiftCtrl-S

        i.e. mash the modifiers together (in any order), follow with a dash, then mash the keystrokes together (order matters).
