Instant
The help overlay says it: Everything else applies the moment you change it: so you can watch the ticker while you experiment. Nothing to save, nothing to undo. Brightness, colorset, the display switches, chart ranges, quiet hours, the address popup rows, the market cards and the notify boxes all go to the ticker as you change them, and the ticker redraws. Frequent live changes are written to the ticker’s storage a little later, in one go, so a run of slider moves does not wear it.
If the ticker cannot be reached for a live change the page says Couldn't reach your ticker just now, nothing has changed on this page. Try again in a moment. and leaves the control where it was; see Couldn't reach your ticker message.

The coin list
The coin boxes are the exception. They wait for Save & Apply Coins, which appears as a green button when the list differs from what the ticker holds. On success the page says Saved & applied to your Ticker.; a refused save says why. See Save & Apply and the coin list.
Reload
Tapping the logo, the Settings heading or the browser line reloads the page from the ticker. If you had unsaved coin edits the page says Refreshed from your ticker, your unsaved coin changes were dropped.; otherwise Up to date with your ticker. See Refresh and reload.
