During VNAV cruise, what happens when ALT INTV is pressed after selecting a higher altitude on the MCP?

ALT INTV is used to intervene in VNAV by using the MCP-provided altitude as the new target. When you’re in VNAV cruise and you dial a higher altitude on the MCP, pressing ALT INTV tells the system to reset the cruise altitude to that MCP value and start a cruise climb to reach it. This keeps the autopilot engaged and guides you toward the updated target, effectively overriding the current cruise leg to begin climbing. It doesn’t disconnect the autopilot, nor does it cause an descent or no change—the action clearly changes the target and initiates a climb to that MCP altitude.
