I’ve owned my Suzuki SUV for six years and just last week figured out that the little tabs under the rearview mirror are switches for nice map-reading lights!
Last winter I found the “secret pockets” in the LL Bean coat I’ve had for 14 years.
Well, I think I sorta kinda understand how to send a text message on my cell phone now. I still don’t wanna, but I feel like I could if I did wanna… Taking pictures, however, still confuses me. 
I don’t have any but I would like to share , when you buy a vehicle, read the owners manual. If it’s used, get one and read it. So many features are built into vehicles these days that there is no way of guessing what they are. I work for a new car dealer and still, every vehicle my wife or I buy, I read the manual. I have found features that I didn’t even know were there. Owners manuals are relatively cheap and are chock full of information you need to know about your vehicle. Please Jennshark don’t think I’m picking on you, because you bring up an excellent point that is missed by almost everyone I see purchase a vehicle.
Agreed Omegaman like I often say RTFM. You will be amazed what you find out.
The other night I discovered that I could hit F11 in Internet Explorer and hide all my toolbars.
And I only recently found the little switches that turn on my oven light and over the stove light on an appliance I’ve owned for almost a year.
And I’m embarrased to admit how old I was when my husband showed me the little crumb-emptying trapdoor on the bottom of the toaster.
They’re very effective, obviously. 
Thank you for supporting my real-life job. (I write manuals. )
My wife and I have owned a 1997 Ford Taurus for 5 years. A few months ago I was cleaning out the trunk and found the 6 disc CD changer located behind a carpeted panel. We always figured the CD changer button on the stereo was on all the Taurus stereos.
Mac computers come with a handy little eject button on the upper right of the keyboard. Nice idea, but it never works! What a useless key. I’ve complained about it on the boards before, I think it was in the “most useless key” thread.
So today I’m ejecting a disc and just for giggles decide to use the eject button and hold it down for a moment or two. Dag! The damn button does work. What’s it been now, three, four years of thinking it doesn’t work? :smack:
I had been the owner of a 2000 Saturn L-Series for several years, and was in Florida to visit the in-laws when I discovered a feature on my car. I was in Gainesville, mid-July, in the parking lot of the Harley Dealership waiting for my now ex-husband to shop for yet another f-ing HD t-shirt. Of course it is hotter than Satan’s anus in Gainesville in the middle of July, but since I didn’t feel like wandering around like a dork in the dealership, I waited in the car with the A/C running full blast. It was fairly cool in there. Since I was bored, I started playing with buttons and hit the one on the climate control panel with the circular arrow. Imagine my suprise when the A/C air suddenly got much colder! Now imagine the sense of stoopid that washed over me when I realized that not only had I owned this car for 3 years, but that this button is on every car. :smack: The rest of the trip was more enjoyable (despite the fact that I was with my nimrod ex-husband).
For anyone else who might not know what this button is: It’s the recirculate button. When your A/C is on recirculate, it uses the air that is already in the cabin (which is already cooled), instead trying to cool hot air drawn from outside. It’s good to get fresh air in the cabin of course, but when it’s that hot, your A/C doesn’t have to work as hard to keep you comfy.
Not something I just found out, but the joy it seems to bring people who didn’t know about it makes it worth mentioning.
You know how you can TAB through web forms?
SHIFT+TAB will tab backwards.
Not just web forms - it’s a Windows standard, and applies to any decently-written Windows application that uses forms.
A well written manual is a joy to behold. You being a doper, I know your manuals are the best out there.
Apparently, yes 
My SIL and BIL, who live like pigs, “found” a 1/2 bath they forgot they had when they did one of their semi-annual shovel-out-the-sty festivals.
I’ve been using the same audio editor since 1998, under various design and name changes. Last night was the first time I ever had occasion to use its vertical zoom. Normally, I use horizontal zoom, to get a close-up view of a part of the waveform. The one I was working on was quite low in volume, and I discovered that if you hit the vertical zoom, it expands the view of the waveform to fill the screen top-to-bottom! I never had to use it before, but now I know what it’s for!
Not to be nosy, but I’d like to hear more on this. They lost a lavatory? That’s epic.
Oh, wow. I love you, man!
People are always shocked as hell when I show them either “Printable View” links or “Print Selection” on the print menu, but I’m sure all Dopers know about that stuff.
I know a family who found a piano in their house they didn’t know they had.
I drove my car for years before I found out that you could roll down the windows remotely by holding down the unlock button on the remote. It’s nice for letting out some heat on hot days.
Thank you! :: blush ::
I found out recently that holding CTRL and SHIFT and using the up or down arrows will highlight a column of items or paragraph. No more mouse-clicking!
