Logitech Bluetooth Mouse

The iPad has no capability to use a mouse.

Not Possible.

NO external Bluetooth mice work on Apple iDevices and iOS.

There is no on screen software pointer/cursor programmed into iOS for an external mouse or trackpad input device to navigate such a software pointer.

Your fingers are your mouse input device.

iOS has an insertion point "I" beam cursor that can now controlled by invoking the iOS software keyboard and then do a two-finger single tap to turn the entire software keyboard area into a giant trackpad area.

You can place insertion "I" beam anywhere you want, then use the delete key to delete a letter and/or replace a letter in a word.

If you use two-finger double tap within the keyboard area, you can highlight words, lines of text or entire paragraphs for editing.

ios does not have a cursor currently so there is nothing to control with a mouse
