First Response & Preservation Technical Explainer
Could moving the mouse or pressing a key alter the evidence?¶
Yes.
Mouse or keyboard input can wake the system, reset a timeout, refresh remote content or send a command to whichever application currently has focus.
The practical rule
Treat every input as a possible live-system action.
The result may not be obvious in advance¶
Examples:
- pressing Enter can execute a command;
- pressing Escape can dismiss a prompt;
- a click can activate a hidden link;
- mouse movement can wake a session;
- a keypress can enter text into a chat or terminal;
- input can reset an inactivity timer.

Photograph before input¶
Capture the whole screen and wider setup first.
Do not press:
- Enter;
- Escape;
- function keys; or
- security-key combinations
merely to test responsiveness.
Attribute necessary input¶
If a bounded preservation objective justifies interaction, record:
- device;
- input;
- operator;
- time;
- reason; and
- visible effect.
The practical point is: preserve the screen first, then treat any mouse or keyboard use as a documented intervention.
