Choose the intended task rather than a label alone
Google describes three shortcut types: Google Home, a favourite TV app and display-device inputs. An app shortcut opens the selected app; it does not certify that an account is signed in or a particular programme can play. Input control changes a different device-selection task.
Write down the intended result in plain language before editing. For example, open the installed player and switch the TV to another HDMI source are different outcomes. A button that changes inputs instead of opening an app can be doing exactly what its current assignment requests.
Create or edit an app or home-panel assignment
Google’s initial setup starts by pressing the unconfigured customisable button and selecting the shortcut type. For an app, select the listed app and Create shortcut, then look for the confirmation message. For Google Home, select that option and confirm the shortcut.
To edit a shortcut, Google documents holding the star button for one to two seconds. Its home-panel note says initial synchronisation can take time; if more than one hour has passed and that specific shortcut still cannot be personalised, the help article recommends restarting the device. This is a scoped condition, not a universal wait for every app shortcut.
Use the special route for an existing input shortcut
If the original assignment displays inputs, Google directs users to All Settings, Remotes & Accessories, Set up remote buttons, Customizable button to choose another type. It also asks that no physical barrier block the remote and display device during this input-control workflow.
During input setup, choose the display device or add it, cycle to the intended input and answer the on-screen question about whether the button worked. Record the actual input result before confirming. A shortcut-created message alone is not a witnessed successful switch to the source you wanted.
Keep hardware scope and account scope distinct
Google says the custom shortcut feature is specific to the Streamer even though remote compatibility has a broader scope. Match the actual box and remote before borrowing this procedure for another Chromecast or a television’s own remote.
No shortcut was configured for this article. After a proposed check, retain the assignment useful to the household and record the target app or display input. An app’s permissions, subscription and programme catalogue remain separate from the remote’s launch function.
