Thank you. Below my thread I found another thread dealing with this issue. I went to Settings and completely disabled instant search.
I strongly advise the design team to consider not interfering with basic operating system keyboard shortcuts. Many rely on these basic keyboard shortcuts. I would not use equipment nor software that prevents me from using them.
Forcing the user to spend time fiddling with settings to restore basic operating system functionality is not reasonable. If the design team wants to use an existing keyboard shortcut for a new feature, offer the user the choice to do so before implementing it on the local machine. All I got was a popup telling me what had happened, with no choice offered.
