If you say so. I think having to wait for the latency of the web search to come back would drive me up the wall if I tried your method.
Win+number row are hotkeys for your taskbar favorites. No explicit setup is required other than having your taskbar favorites ordered how you want them. Pressing the hotkey will open the program if it's closed, focus the program if it's in the background, or minimize the program if it's focused.
RPN is the best. It's mostly just doing math in the order it would be calculated anyways, so IMO, it's far superior for learning (which is 99% of the time any normal person uses a calculator).
I still have the same scientific calculator I used in high school. All the markings on the keys have long since worn off, but my muscle memory is so strong that I am speedy and accurate in typing.
For isolated, unimportant calculations, I'll use my phone or the calculator on my computer, but for anything more than that, I relish the chance to use my proper calculator. I think using it puts me in a particular frame of mind where I'm more focussed too, like my brain is going "okay, let's buckle up, it's maths time, let's have no silly mistakes, keep on task"
...yes? The spotlight/quick search tool is stupid useful. Everything is just a quick alt-space and a type away
I've been using Synapse on Linux for years and Windows powertoys is way better than this nonsense (which is super confusing because that's also an official Microsoft programme. Why do they have a superior version of their search that you have to seperately download?)
Since I pretty much always have a browser open I just use the search bar to do it unless I know I'm doing multiple operations, then it's off to the pinned calculator shortcut
