Portal Sandbox Regeneration: E and Input Fixes

Portal Sandbox regeneration has a normal-use question and a troubleshooting question. Start with E when you need the recovery control. Use the failure guide when you need to distinguish the wrong key, blocked input or an outcome that was different from what you expected.

Recovery inputE selects Regenerate; Q belongs to Knife.

All regeneration guides

Using the recovery action and checking failures.

Use recovery deliberately before diagnosing it

The normal guide puts E beside the weapon you intend to practise and keeps it distinct from Q for Knife. It does not turn regeneration into a promise about survival or exact timing. The troubleshooting article is for a repeated symptom: confirm the action, check focus and menus, then separate no response from a visible response with an unexpected outcome. Read the page that matches your situation. Once the input is familiar and responsive, continue to the encounter or weapon task you actually wanted to improve instead of staying in a troubleshooting loop.

Questions about regeneration

Is Q the recovery input?

Q is Knife; E is Regenerate. Correct that neighboring-key mistake before treating an unexpected weapon selection as a failed recovery action. The full controls page lists the rest of the toolkit.

Does using E guarantee survival?

Plan to select the recovery action deliberately, but do not turn the binding into a promise about invulnerability or every incoming attack. If the result is unclear, describe the input and visible outcome separately before calling it a technical failure.

Bring recovery into an encounter

The PvP guide connects a chosen weapon, regeneration and a separate travel input after the normal recovery key is familiar.
