Snippets
CommandPost allows you to create Lua code snippets, which appear as actions in CommandPost's Search Console.
This means you can trigger a snippet via a shortcut key or control surface button.
For example, to launch Final Cut Pro, you can use this simple Lua code:
cp.apple.finalcutpro:launch()
CommandPost is also compatible with Hammerspoon, so you can also use any of the examples on the Hammerspoon website:
​http://www.hammerspoon.org/go/​
You can learn more about Lua here:

Here's a link to Hammerspoon's API reference:
​http://www.hammerspoon.org/docs/index.html​
Here's some direct links to some useful Hammerspoon functions:
​hs.timer.usleep(microsecs) - Add a delay
​hs.eventtap.keyStroke(modifiers, character[, delay, application]) - Trigger a virtual key stroke
​hs.application:selectMenuItem(menuitem[, isRegex]) - Trigger an application menu item
Examples
Forcefully restart an application by its bundle identifier
local bundleID = "com.logitech.manager.daemon"
local apps = hs.application.applicationsForBundleID(bundleID)
if apps and apps[1] then
    apps[1]:kill9()
end
hs.application.launchOrFocusByBundleID(bundleID)
Select all even clips in a timeline
cp.apple.finalcutpro:launch()
local clips = cp.apple.finalcutpro:timeline():contents():clipsUI()
table.sort(clips, function(a, b) return a:position().x < b:position().x end)
local evenClips = {}
for i, clip in ipairs(clips) do
    if (i % 2 == 0) then
        table.insert(evenClips, clip)
    end
end
cp.apple.finalcutpro:timeline():contents():selectClips(evenClips)
