I’ve been using Leopard for long enough now to collect five tips that save me time and effort. Let me pass them on to you.

Find emails faster in Leopard Mail

Before Leopard it was possible to find emails in the list view of a mailbox faster by using the Mail Type Select plugin. With this installed, Mail.app jumped to the first message that matched your keystrokes, just as Finder does. So typing “Ros” quickly found the first email in the mailbox from Rosemary.

Now this feature is built into Leopard Mail by default. Try it out. It makes a difference.

Do your sums faster

Now that I am a Dean and need to set and manage budgets, I need to do sums more than ever before. A nice new feature in the Spotlight window, does your sums for you.

Just type in an equation, say, “12 * 34″ and Spotlight goes to Calculator and does the sum for you, giving you the answer in the Spotlight results. Nifty.

Edit iCal to-dos and events faster

In Tiger you could edit events and to-dos from the information pane. Now, iCal’s sidebar has gone to God. To edit an iCal item, you need to double-click it, wait for the details pane and then click again on the edit button on the bottom.

These extra clicks add up over time. Especially if, like me, you live in a fluid world in which tasks and meetings are always changing.

Luckily, there is a short cut to get straight to editing an event or a to-do.

Click once on the iCal item to highlight it. Then press ⌘-e (Command + ‘e’) and you launch into an edit dialog straight away.

Create better iCal events in Mail faster

Hovering the mouse over a name or details of an event in Leopard Mail activates Leopard’s Data Detector and produces a drop box with the option to add it to Address Book or iCal.

That’s pretty smart, but there is something even smarter lurking here.

If you block all a contact’s information before you hover over the name, for example, or details of an event for iCal, the data detector pastes all the information into the new contact’s or event’s notes field.

Get more out of iCal’s Dashboard Widget

The iCal Widget in Leopard has a secret up its sleeve. If you click on it once, it displays the monthly calendar we all knew and loved in Tiger.

Click on it once more, and it pulls your events for the day out into a third pane:

I get this information more easily from MenuCalendarClock, but if I didn’t have it, I’d value it here. UPDATE: Thirty seconds after posting this I found a smarter Dashboard solution.
