Arrow Keys on ios

Keys K_LEFT or K_RIGHT do not do anything on ios (though the ios custom keyboard interfaces would support this)

Can you give me some more detail on what you are expecting here? Have you created a keyboard layout that has [K_LEFT] and [K_RIGHT] keys on a touch layout? Or something else?

Yes, exactly, I have created a keyboard layout that has [K_LEFT] and [K_RIGHT] keys on a touch layout. I expected the cursor to move left and right when touching these keys (as I know it from other custom ios keyboards).

Makes sense. I’ve created a feature request issue at https://github.com/keymanapp/keyman/issues/1573 to track this.
