Stairways Software has released Keyboard Maestro 4.3, a notable update to the company's essential macro software. New in 4.3 are "device triggers" that can activate macros based on actions from modifier keys, mouse buttons, and programmable keyboards. Other changes enhance Keyboard Maestro's AppleScript integration, so results of AppleScript (and shell) scripts can now be typed or pasted into the current selection. Plus, although AppleScript scripts no longer lock up the Keyboard Maestro engine while executing, they also no longer allow user interaction without help from another application (like System Events). The update also fixes a few obscure bugs, such as one that could cause a crash if you deleted a named clipboard while editing the clipboard's name. Full release notes are available.

Extend Mac OS X's Screenshots
Mac OS X has a variety of built in screenshot methods. Here's a look at a few that offer more versatility than the basic full-screen capture (Command-Shift-3):
• Press Command-Shift-4 and you'll get a crosshair cursor with which you can drag to select and capture a certain area of the screen.
• Press Command-Shift-4-Space to select the entire window that the cursor is over, clicking on the window will then capture it. The resulting screenshot will even get a nice drop shadow.
• Hold down the Space bar after dragging out a selection window to move your selection rectangle around on the screen.
• Hold down Shift after dragging out a selection to constrain the selection in either horizontal or vertical orientation, depending on the direction of your drag.
• Hold down Option after dragging out a selection to expand the selection window around a center point.
