I try to enlarge my tiny digital keyboard but it keeps typing accented letters when I zoom in what to do????

Have you enabled the Scribble feature? This feature uses a different mini-keyboard that does not respond to the two-finger zoom or pinch gestures.

Settings > Apple Pencil > Scribble - set to OFF

After disabling Scribble, you may need to force-restart your iPad:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

Otherwise, to restore the new Floating Keyboard to the normal on-screen keyboard presentation, use the two-finger “zoom” gesture (i.e., the reverse of the two-finger “pinch”).

If the Split Keyboard is restored instead of the full on-screen keyboard, you can either use two fingers (one on each of the two half-keyboards) and swipe the two halves together - or touch-and-hold the “keyboard” key, then slide your finger to the Merge & Dock option and release.

After ANY iOS/iPadOS upgrade/update, you should ALWAYS perform a simple hard reset/forced restart of your Apple mobile device.

For iPad models with a Home button, do a simple hard reset/forced restart of your iPad by holding down both the Home and sleep/wake/power button simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.

OR

For much newer design iPad models, without a Home button, try the new simple hard reset/forced restart procedure for the new 2018-2022 iPad Pros, 2020/21 iPad Air 4 and 5, the 2021 iPad Mini 6 and the new 2022, 10th gen base models,

1. Press and release the volume button closest to the top Power button

2. Then immediately ( and quickly ) press and release the volume button farthest from the top Power button.

3. Then, press and hold the top single sleep/wake/power button You will see the Slide to Power off button, but keep on holding down the power button until you see the Apple logo, then let it go.

Once you have performed all the steps, wait for a few seconds and your 2018-2022 iPad will boot up completely to the iPad’s Lock screen.

Best of Luck to You!

try doing the two finger pinch outward at a diagonal.

See if the keyboard enlarges back to full screen when doing that.

Do it smoothly and not hold on any of the keys.

Best of Luck to You!

Use your thumb and first finger on the keyboard and spread them out in slow, but continous outward spread motion.
