Menu Commands and Keyboard Shortcuts

This chapter explains the function of each of the items found in OmniPlan’s drop-down menus, and lists default keyboard shortcuts for them where they exist. To add shortcuts for commands without them, see Adding Keyboard Shortcuts.

The File menu contains commands related to OmniPlan on a project data level. Create new documents, and copy, save, duplicate, restore, or otherwise manage existing ones. This menu also provides commands for getting data out of OmniPlan: printing, exporting, and reporting, publishing, and more.

The Edit Menu

The Edit menu holds commands related to modifying the contents of tasks, resources, calendar blocks, inspector field values, and more. Cut, Copy, Paste, and Undo are all found here.

Undo (Command-Z)
Reverse the most recent change you made. You can keep stepping backwards like this if there are more changes you want to undo.
Redo (Shift-Command-Z)
Reenact the last change you undid. You can keep stepping forward through however many Undo commands you made.
Cut (Command-X)
Remove the selected text or items, putting them on the clipboard so you can paste them somewhere.
Copy (Command-C)
Put a copy of the selected text or items on the clipboard, so you can paste them somewhere.
Copy Link To Task
Put a link to the selected items on the clipboard. When you paste it, you get an OmniPlan URL that opens the project file and highlights the selected items.

Accessing Items by URL

OmniPlan supports URLs (links) beginning with omniplan:/, most commonly created with the Copy Link To Task menu command. When you open such a URL, OmniPlan opens and highlights the specified item.

For example:

omniplan:/Volumes/Local/Users/someone/Desktop/Coffee%20Plan.oplx opens the Coffee Plan project on the user’s desktop.

omniplan:/Volumes/Local/Users/someone/Desktop/Coffee%20Plan.oplx/task/14 opens the project and highlights the task that has the unique ID of 14.

omniplan:/Volumes/Local/Users/someone/Desktop/Coffee%20Plan.oplx/task/14,22,67 opens the project and highlights the tasks that have the unique IDs of 14, 22, and 67.

You can also make URLs which query for certain values other than ID:

omniplan:/Volumes/Local/Users/someone/Desktop/Coffee%20Plan.oplx/task?title=Clean%20Up opens the Coffee Plan project on the user’s desktop and highlights any task titled “Clean Up”.

omniplan:/Volumes/Local/Users/someone/Desktop/Coffee%20Plan.oplx/task?name=Clean%20Up also opens the project and highlights any task titled “Clean Up”.

omniplan:/Volumes/Local/Users/someone/Desktop/Coffee%20Plan.oplx/task?position=1.9.1 opens the project and highlights the task at outline position 1.9.1. Note that the URLs use hierarchical numbering regardless of whether you have hierarchical or flat numbering turned on in the View menu.

A file must be saved in a location that the OmniPlan sandbox can access before it can be the target of an OmniPlan URL. OmniPlan URL link paths are absolute, so moving a file from one location to another breaks any links to it.

Paste (Command-V)
Take whatever’s on the clipboard and insert it at the current selection. If the clipboard contains only text (not whole items), and you are editing the text of an item, the text is pasted at the insertion point. Otherwise, the contents of the clipboard are pasted as new items.
Delete
Remove the selected item(s) or text from your document.
Select All (Command-A)
Select everything in the outline, or if you are editing an item’s text, all text in the cell.
Deselect All (Shift-Command-A)
Clear the selection completely so that nothing is selected.
Duplicate (Command-D)
Make another item just like the selected one, immediately after it.
Edit Note (Command-’)
Move from the item text to the note area of an item, or move back from the note area to the item text.
Add Link to File
Choose a file to link to the selected item (or the project as a whole, if nothing is selected), adding it to the list in the Linked Files inspector. Linking a file does not embed it into the project; like a website address, it creates a reference to the file elsewhere on your system.
