What should you do? First, stop dragging your mouse! To stop the "runaway mouse" add some keyboard shortcuts. To begin, move to the top of the area you want to highlight. Then, press and hold down [Shift]. Move to the end of the area by pressing any directional keys such as the [Down] arrow or [Page Down]. Keep holding down [Shift] and continue moving to the end of text or data that you want to highlight. When you have the area you want then perform the next action: formatting, editing, etc.

Still like the mouse? Press and hold [Shift] and click to pick the end of the selection area even if it is at the end of the document. The key is not to drag; use the scroll bar if you need to make big moves.

Excel bonus: Okay, I admit there is a dragging trick in Excel. Instead of pulling harder on the mouse to move to the end of the selection, stop on the scroll bar. If you hop on and ride the scroll bar and gently pull the mouse, you can easily maintain control.

Easy Keyboard Selection Secret
Even better than the [Shift] key is a hidden selection trick. I compare this to taking the measurements of a large room--it's much easier with a friend holding the measuring tape at one end while you take your time to move to the other end. Ever have a measuring tape snap back when you try this yourself? The hidden trick is the [F8] function key.

To use this selection trick, simply:

1. Move to beginning of the selection area.
2. Press [F8] once.
3. Look in the bottom center or left corner of your status bar for EXT; don't expect anything to flash or pop up; EXT stands for Extend Selection.
4. Take your time moving to the end of the selection area with your keyboard and/or the mouse.
5. Perform the action to the selected area such as formatting, cut, copy, etc. The EXT mode turns off as soon as you do an action. Just move anywhere to clear the highlight.

What if you change your mind and you want to turn off the Extend Selection without continuing? In Excel, press [F8] again or press [Esc]. In Word, press [Esc] to cancel. Move anywhere to clear the highlight.

Selecting Multiple Items
To select more than one item such as 2 different paragraphs in Word, 4 cells in Excel, 3 graphics in PowerPoint, or 10 files in Windows Explorer, choose either [Shift] or [Ctrl]. The basic steps work in Microsoft Office, Windows Explorer, and many other Windows programs.

To select a contiguous (touching) area use [Shift]:

1. Click once on the first item.
2. Press and hold [Shift].
3. Click on the last item that you want to highlight and everything in between will also be selected.
4. Perform an action such as formatting.

To select non-contiguous (unrelated) items use [Ctrl]:

1. Click one on the first item.
2. Press and hold [Ctrl] and, click on each of the other items, press [Ctrl] again to unselect.
3. Perform the action to finish working with the highlighted area. Some ideas for these options:

• Pick files from the Open dialog box to open all of these at the same time in your Microsoft Office program.
• Choose multiple slides in the PowerPoint slide sorter to apply a transition.
• Highlight groups of cells or sections of text and apply formatting.
• Select drawing objects to group, move, or change formatting.

Selecting Tricks in Word With the Selection Bar
Have you ever used the selection bar? Just think of this as the left margin of your Word document. To locate the selection bar area, move your mouse to the left of text until it changes from an upper case "I" to a white arrow.

• Click once to highlight entire line.
• Double-click to select the whole paragraph.
• Triple-click (can you do it?) to highlight the entire document (great for overall changes such as font formatting).

Easy Select All
To make changes to an entire document or file, press [Ctrl] + A to Select All or choose File > Select All (in Office 2003, if available).
