There are two ways to do this:
- Press and hold the Language Chevron
- Press the Eject Key
Both of these methods require you to select the text field. Simply tap the field to select it. If not selected, the on-screen keyboard won’t appear.
When you’re in a text field, the keyboard toolbar will show at the bottom of the screen. Press and hold the Language Indicator (“EN” shown below) to bring up the context menu then select “Show Keyboard”
If you’re using a keyboard and it has an Eject key, simply select the text field and press “Eject.”
