Hello,
The question is easier to understand by starting with an example. This is under Windows, I don't know if the behavior is the same in other O/Ss.
Click anywhere on an editor window of a file that is being edited. The caret will be, as expected, where the click occurred.
Press the Alt key (just the Alt key, nothing else), this should cause the first menu that is accessible using Alt to be selected. Press the Alt key again and the menu is deselected and the editing caret/window is active again. Repeat that and, it becomes quite evident that successive presses of the Alt key toggle back and forth from the editor window to the menu.
Now, instead of pressing just the Alt key, press simultaneously Alt and Ctrl. this causes the mouse cursor to change and, releasing and pressing Alt-Ctrl again does NOT make the editing window back active. Instead it seems the only way to make the window active again is to click on it.
Is there some setting in Lazarus that would cause it to be a toggle instead of having to click the edit window ? IOW, make Alt-Ctrl be a toggle just like Alt by itself is ?
Thank you for your help.
