M23 Edit: Looks like it cannot be done - the styles are seemingly among those that cannot be altered dynamically. Even MSDN suggests the delete/create method.

There is known bug/limitation in Send/ControlSend with national keyboards, escpecially with Czech one. One workaround is to switch keyboard to english then use Send/ControlSend and then switch it back. More elegant solution in your example is to use COM commands for all desired actions instead of Send/ControlSend. Search MSDN for Range/Copy/Paste and look at Excel.au3 sources to get idea and instead of +{F11} use _ExcelSheetAddNew()
