It shouldn't be, but the
tell application block is a stumbling block, right at the start of drafting an applescript.
On my system, for example,
tell application "OmniFocus"
works, but
tell application "OmniOutliner"
fails, and so does
tell application "OmniGraffle"
Not only do you have to memorize some slightly arbitrary and inconsistent elaborations like:
tell application "OmniOutliner Professional"
tell application "OmniGraffle Professional 5"
but these references stop even very simple and general scripts from working across variants and versions of the same app (Professional versus vanilla, Ver. N versus Ver. N + 1)
Apple did introduce an improvement around OS X 10.5. Developers, they argued, are unlikely to change an application's 'bundle identifiers' and 'creator codes' across successive versions, whereas they do have a habit of changing its name, and so they introduced the format:
tell application id "com.omnigroup.OmniGrafflePro"
which looked promising because it didn't contain a version number.
And thus I personally generally switched to forms like:
tell application id "com.omnigroup.OmniFocus"
Which was fine, until I learned that the new AppStore versions have variant bundle names like
com.omnigroup.OmniFocus.appstore and therefore choke on any applescript which starts with a line like the one above ...
So do we sigh and return to things like:
tell application "OmniGraffle Professional 5" ?
This makes sense if code is genuinely version-specific, but is frankly annoying in the numerous cases where the code for OmniOutliner and OmniOutliner Professional, or Omnigraffle vanilla, professional, or version whatever you like, would actually be identical ... (Two versions of OmniOutliner in the same office, professional and plain, and a need for a simple script which would run on both, for example).
This is why I am generally switching to a third application reference variant, which uses
tell application id + creator code. Thus, for example:
tell application id "OOut"
for any version of OmniOutliner, and
tell application id "OGfl" for any version of OmniGraffle.
I have even adopted the reflex of
tell application id "sevs"
in place of
tell application "System Events"
All very well, but how do you learn and remember all these four-letter codes ?
Here is a script which will show you the four-letter creator codes (and the longer bundle identifiers) for all the applications currently running on your system. If you want, you can enter a search string, to filter down the list.
It will place a creator code (or bundle identifier)
tell application block, for a selected application, in your clipboard.
(Ver .04 below should be compatible with LaunchBar and Keyboard Maestro. Tap space bar to pass a search string to it directly from LaunchBar).
Code:
-- Get creator codes and bundle identifiers for tell applications blocks
-- (for applications currently running
-- Ver .05 Compatible with LaunchBar - select script, tap space bar and enter string in Launchbar

property pDefaultSearch : "omni"
