To prevent the mouse from moving during a double-click, bracing the mouse by putting the thumb on the side of the mouse and the bottom of the hand on the bottom of the mouse. In Windows, the threshold of movement can be increased by changing the associated registry keys in HKEY_CURRENT_USER/Control Panel/Mouse Additionally, applications and operating systems will often not require the mouse to be completely still. Instead, they implement hysteresis, allowing for a small amount of movement between the two clicks. Another complication lies in the fact that some systems associate one action with a single click, another with a double-click, and yet another with a two consecutive single clicks. Even advanced users sometimes fail to differentiate between these properly. An example is the most common way of renaming a file in Microsoft Windows. A single click highlights the file's icon and another single click (on the filename, not the icon) makes the name of the file editable. A user who tries to execute this action may inadvertently open the file (a double-click) by clicking too quickly, while a user who tries to open the file may find it being renamed by clicking too slowly. This may be avoided by Windows' users by using the menu (or F2/Enter) to initiate renaming and opening rather than multiple clicks. In GNOME, this problem is avoided entirely by simply not allowing file renaming by this method. In the classic Mac OS, which originated this technique, moving the mouse after the first click would immediately highlight the name. This was the result of a bug in the first versions of the system, one that was deliberately continued after users had come to rely upon it. Speed and timing The maximum delay required for two consecutive clicks to be interpreted as a double-click is not standardized. According to Microsoft's MSDN website, the default timing in Windows is 500 ms (half a second). The double-click time is also used as a basis for other timed actions. The double-click timing delay can usually be configured by the user. For example, adjusting double-click settings can be done by: Windows XP, Windows Vista and Windows 7 - Start > Control Panel > Mouse > Buttons (Start > Control Panel > Printers & Other Hardware > Mouse > Buttons if Control Panel is in Category view). If you prefer, you may use Start > Run > main.cpl. macOS -
