You can use the iPad onscreen keyboard in split mode with Horizon Client when you connect to a server and when you are working in a remote desktop. This feature is supported on any iPad model that supports the split keyboard feature.
To split the onscreen keyboard, tap inside a text field, touch and hold the Keyboard key in the lower-right corner of the onscreen keyboard, and tap Split. To merge a split keyboard, tap Merge.
When the onscreen keyboard is in split mode, the space between the two parts of the onscreen keyboard is transparent.
When the onscreen keyboard is in split mode, the accessory key bar is not available. To make the accessory key bar available, you must merge the keyboard.
