Zoom to `Midi Item` in Piano roll

When I click on `Midi Item`, the piano roll appears. Is it possible to make automatically (or using keyboard shortcut) stretch events in piano roll horizontally so I could see them all?

I made a screen cast to show visually what I meant

There is an action on the midi action list to do this:- size to fit content. This will do want you want, just assign it to a shortcut.

doubleclick the horizontal-scrollbar in the midi editor.

It's double clicked into history now. You learn something new everyday. Thanks Kainer.

You could make a custom action. Open midi editor. size to fit content. Which would them make it your default! If they were in one window, what a shame. Doh

I used to use this macro for such task: *SWS: Save time selection, slot 1 *SWS: Select only track(s) with selected item(s) *Track: Set first selected track as last touched track *Track: Vertical scroll selected tracks into view *Time Selection: Set time selection to selected items *Move cursor to start of time selection *View: Zoom time selection *Item: Open items in primary external editor *Time selection: Remove time selection *SWS: Restore time selection, slot 1 With this macro I could open several MIDI Items at once, place the edit cursor at item's left edge to play and zoom.

The SWS Actions are in the SWS Extension module - you download it separately and put it in your Reaper Program Plugins folder (C:\Program Files\REAPER\Plugins here). SWS Extensions:

Woah! Those additions are superb!
