If you are using a touchpad, trackpad, or pointing stick, or if you
have arthritis or other difficulties using the mouse, you may find it
difficult to hold the primary button down while moving the mouse.
However, this can be used to select text, move open applications around
the Windows 7 Desktop, and drag and drop files via Explorer.
For assistance with this technique, you can turn on a feature called "ClickLock". This lets you briefly hold down the primary mouse button for a half second or so, and then you can move the mouse to select text or move an item. Click the button once again when done with your text selection or item movement.
1. Click the "Start" button.
2. Type "mouse settings" (without the quotes) and click the option "Change mouse settings".
3. When the "Mouse Properties" dialog box appears, click the "Buttons" tab.
4. Underneath "ClickLock", check "Turn on ClickLock".
5. Click the "Settings" button.
6. A "Settings for ClickLock" dialog box appears. If you find ClickLock taking too long to activate, click on the thumb slider to the left of the thumb to move it towards "Short". On the other hand, if you find windows or text being selected too often, click to the right of the thumb to require a longer holding down of the mouse button to activate this feature.
7. Click "OK" on the dialog boxes to close them.
To disable this feature later if desired, repeat steps 1-3, uncheck "Turn on ClickLock", and press "OK" to close the dialog box.
