Alt Key Shortcuts Causing Problems

Setting aside the PS, the problem is the way Alt+Tab works. For the last 30 years, it has a standard way of working on Windows for switching applications. For example, open Word and Excel and then Alt+Tab between the two. You'll see how it is smooth and the cursor is exactly where it was left before switching. The shortcut keys are not displayed until the application has focus and THEN you press the Alt key. Power BI doesn't follow this standard. In fact, it is inconsistent even in Power BI. e.g. Alt+Tab between any other application and then PBI. The first time, the shortcut keys show and the second time, they do not. This is clearly a bug. Shortcut keys should not show until the application has focus and then press Alt (no Tab).
