What are some gestures or shortcuts you use on a daily basis that you can't live without?
I've found the BetterTouchTool preference pane add on to be great for creating custom gestures on a per app or universal basis
Sleep all displays:
Capture Screen shot:
⌘+⇧+3 (captures entire screen immediately)
⌘+⇧+4 (draw a rectangle to capture)
⌘+⇧+4, then space (click a window to capture)
Add ctrl to any of the above to copy to clipboard, rather than saving a PNG to the Desktop.
Seems like a silly question for Stack Exchange, but here goes. And I'll be more realistic than most folks.
Do it and don't ever tell the victim how to undo:
ctrl+⌥+⌘+8 (only until Lion) (spoilers)
Couldn't possibly live without it, above all. It was fun while it was default... :-(
So, I'll add a handful of spoilers below on how it could still be done.
Unfortunately it now comes disabled. To re-enable it, find Keyboard Shortcuts Accessibility.
Or, after OS X 7, it won't be as smooth (even if you do practice positioning the mouse):
⌥+⌘+F5 then select Invert Display colors (apple article)
⌘ + ~ to move between open windows in the current application
With Quicksilver, I added a ton of keyboard shortcuts for programs and folders, such as:
Ones I use most that are native to Mac:
⌥+⌘+⇧+V to PASTE AND MATCH STYLE
(paste plain text, maintaining formatting of document you are pasting into) - if supported by the program
Three finger swipe left or right to move between tabs in my browsers.
Configured this universally through BetterTouchTool - it simply activates the appropriate keyboard shortcut
⌘ + ⇧ + ⌫ = Empty trash.
There's something satisfying about hearing that trash emptying sound : )
⌘ + , to open the current application's preferences. Works in practically every OS X app that has a preference pane.
By comparison, in Windows preferences don't have a common shortcut and the menu entry, typically labelled either "Preferences" or "Options", can be found pretty much anywhere in the menu hierarchy (although often it's in one of Edit, Tools or View). Command-comma was one of the things I really loved when I switched to OS X.
These are my current BetterTouchTool settings:
There are only a few I couldn't live without…
⌘+\ <- Using visor, I've got terminal set to drop down from the top half of the screen. I use it very, very often
⌘+ctrl+D <- Dictionary - works most of the places I need it to.
⌘+space <- Spotlight - Invaluable.
I may be moving away from terminal, and towards iTerm2. iTerm2 has the same functionality built into it.
No one seems to have mentioned the ⌥ keymodifier very much!
⌘ +W Closes a window
⌘+M Minimises a window
Throw ⌥ in with these and it will apply the command to all windows in that application!
⌘+⌥+W Closes all windows in current app
⌘+⌥+M Minimises all windows in current app
Bonus tip: Hold ⇧ to slow down practically all window animations (minimise, Exposé, etc).
⌘ + ⇥ to switch between open applications
Safari or Chrome
The three finger swipes, work in most apps which have tabs or tab-like interface i.e. Web Browsers, Terminal, iChat, etc
The rotate right/left gesture is kind of like your twisting a bottle-cap on and off. I use this to switch between tabs if I'm just browsing the web.
This makes closing and reopening tabs super easy. With a three-finger click I can close a tab, and a two finger swipe up I can reopen it. Quick access to tab history is great when you've got lots of projects happening in lots of windows.
I'd rather use KeyCue from Ergonis Software which helps me find all the shortcuts and gestures an app can have. Check it out here!
But my favorite commands remain ⌘ + ⇧ + F in the finder to create smart folders.
