Was Windows the first to allow this, or was there some antecedent? There are 'modern' Linux GUI toolkits which still do not allow this, like GTK's GtkFileChooser which apparently lives in the dark ages (no thumbnail support there either).
Holding Shift while opening context menus usually show more advanced options, like the possibility to run as another user when right-clicking something executable.
Firefox: If you try to drag the mouse to select part of a link it you drag the link (so you can place it on the bookmarks toolbar/etc), to prevent this behavior you can hold Alt and now it'll let you select the text without dragging the link (this one is not windows specific, it works on Linux too).
F3: find
Alt F4: close window, ctrl-w seems to do this a lot these days too
Alt minus: show child document window menu
Alt space: show window menu, useful if you remember the X for maximize/minimize, z for resize, m for move, r for restore immediately afterwards.
F4 go to address bar in Explorer
F5 refresh
Ctrl F6 switch windows in MDI interface
Ctrl escape: show start menu
Shift-F10: right click menu
Windows E: explorer
Alt-up in explorer: go to directory above; backspace/alt-left: go to previous history item
Windows W windows ink for annotation
Windows R for run
Windows U for narrator
Windows F used to do find but now shows the feedback tool, which I think is a loss
Any command after the word control will open control panel to the right place, eg control display
Windows D show desktop toggle
Windows M minimise all windows, windows shift M restore windows
Ctrl-shift-escape: show task manager
Ctrl tab/ctrl-shift-tab move to next/previous UI item so you can use the UI with a keyboard; this is why web apps that pretend to be native are so useless and annoying because this doesn't work
Also system items normally end with .msc to open the management console, eg. Compmgmt.msc. There's a load of these that help you get to the nitty gritty of the system.
Turn on "show accelerators" in accessibility and menu entries and buttons will have their accelerator underlined, eg the O in OK or F in File. You can then use alt-(letter) to go to it, eg alt-f to open the file menu, s for save.
Honestly I don't know how I would have got through using Windows for decades without these shortcuts. I always find the Mac relies on mouse usage a lot more and the ctrl-F2 and ctrl-F3 shortcut to get to the menu bar and dock on Mac doesn't compare.
- The window snapping shortcuts win + left or win + right are great. - Alt-tab rolls through all open windows, not open programs (avoids the tab + ` in mac) - Win + e to open explorer that one comes in handy often
You can drag the icon from any title of a window into a finder window or dialog to go to that directory.
You can right-click on the title bar of any window and see the path to that window's document.
But enjoy Windows!
