When an application that uses hotkeys starts, it registers the hotkeys with the operating system. After that, no other application can use the same hotkeys. If another application has registered the same hotkeys that Snagit uses before you start SnagIt, SnagIt will display an error about a hotkey conflict.
Change the current hotkey configuration
To configure the SnagIt hotkeys, select Tools > Program Preferences > Hotkeys. Then select a different combination or None from the menu.
