If you are using Compiz Config Settings Manager (CCSM) You can use the ' Commands' Plugin to ' Assign bindings to arbitrary commands'. The ' Commands' Plugin can be easily installed by dropping the next in a terminal: sudo apt-get install compiz-plugins-extra.Its powerful key grabber may have better chances to catch the custom keyboard buttons presses in order to provide the proper key binding which can be assigned to the proper command in the list. A Key Binding for a command, this is: ' Run command 0' will invoke the line that you write in the Commands section related to the ' Command line 0'.In the ' Commands' tab of the ' Commands Plugin', we write the arbitrary commands that we wish to be executed when we hit the proper key or key bindings, as shown in the next screenshot:Then we click on the ' Key Bindings' tab of the same window in order to enable the proper key bindings for the command. Please notice that I placed the command for the calculator in the ' Command line 1' thus the key bindings will be which corresponds to the ' Run command 1' as shown in the next screenshot.What I did to see the ' Edit Run command 1' key bindings it was to click in the ' Disabled' button to the right, which showed me a window with a checkbox, after enabling it showed the options. Then simply hit the 'Grab key combination' and press the proper button in your keyboard. Please notice that the key bindings corresponds to the ' XF86Calculator' key.This way you can define as many custom key bindings to fit your needs.Good luck!P.S.
Compiz Config Settings Manager can be installed from the Software Center or by dropping sudo apt-get install ccsm in a terminal. Edit: Sorry, I somehow managed not to see that you are using KDE. This answer is for Xfce.Afaik these keys can be assigned the same way as any other keyboard shortcuts:Go to Settings - Keyboard - Shortcuts for Applications. (or similar - I'm using the German localization).
There should be a button to add new custom keyboard shortcuts.The first dialogue that pops up after pressing the add button will ask about the command that should be run. I don't know by heart, which calculator is installed on Xubuntu, but you can try to enter xcalc as command name, or maybe gnome-calculator.The second dialogue will then record the key you press. System Settings - Shorcuts and Gestures - Custom ShortcutsEdit - New - Global Shortcut - Command/URLOn Action tab Command/URL: type 'kcalc'On Trigger tab, click the button (possibly labelled 'None') to enter a keyboard Shortcut.Note that you may generalize this to use any calculator program (or any program) if you know the command that launches it - the above uses 'kcalc' as an example.I believe this is the only answer so far that works for KDE (as asked for) without some additional special package installed.Thanks to user lueck at the below reference, for this info.
They’re fun for spelling out rude words and passing the odd GSCE test, but do you actually know what the rest of those buttons do on a calculator?No? Well me neither and after about the first line, all the symbols began to look like Serbo-Croat acronyms. So I decided to spend the morning researching and compiling this little guide on what the rest of the buttons actually did to an extentMathematicians and those with more than GCSE in the subject, feel free to add more or fill in the gaps as to what’s been missed.For the rest of us mortals, class is in! This is a guide for a standard calculator, scientific or graphic calculators may have different/a lot more functions which take even longer to explain.Let’s start with the basics.
I’m going to assume we’re all on the same page with the Numbers- 0-9 and the basics +,–,x and =.OK, let’s step it up a gearAC – All Clear/Turn on– This will wipe any previous equations on the calculator and take you back to 0. This can also be CE.C – Clear– The C button erases the last number or operation entered, use it if the last number you entered was a mistake.DEL & INS Delete and Insert- Delete will delete individual characters, so you can alter complex equations without clearing the whole formula. Insert allows you to re-enter numbers over a formula, like on a PC keyboard.+/- Plus/Negative – This changes the number on screen to a plus or negative%- Percentage of a number or percentage in an equationΠ or pi- 3.14159 (continued depending how flash your calculator is)√- Square root.
This button will show the square route of a displayed number.X 2 – Square- The x2 button computes the square of the number currently displayed. 5×5)X 3- Cube.
Computes the cube of the displayed number (e.g. 5x5x5)Ok, next step MemoryMS or MIN = Memory Store puts the number on the display into the memory to save.
This is useful if you have a number that always needs adding to an equation- Like if every equation needed a shipping fee of 4.5 adding.M+/M- = Memory Add (or Subtract) takes the number on the display, adds it to the memory, and puts the result into memory (or subtracts)MC = Memory Clear will reset the memory to zeroMR = Memory Recall uses the number in memory, acts as if you had keyed in that number yourselfRCL = Recall the number last in the memory and displays it.Mixed fractions and parentheses getting more trickya b/c =Mixed Fraction. This button allows you to insert a mixed fraction. Like 1 and 1/3.LOG – LOG is used in logarithms for changing the base fraction. I am not even going to pretend to know about logarithms, so here’s to someone much cleverer.( ) Left and Right Parentheses- Or brackets to you and me.
These are for prioritising equations. For example (2+6 )x3 is 24 but 2+(6×3) is 20.Trigonometry– yeah it’s getting a bit complex nowSIN COS & TANSine, Cosine and Tangent are all used in trigonometry. They are used to establish a number from an angle, in a right angled triangle. To work out a SIN/COS/TAN you need to know the hypotenuse, opposite and adjacent.Sine, Cosine and Tangent are opposite corners of the triangle. To find the number out divide the length of one side by another side.
So for COSINE divide the Adjacent and the Hypotenuse.HYP is used to select Hyperbolic functions. Without studying calculus, it won’t make a whole lot of sense, it didn’t to me HYP makes the three above function Hyperbolic so sinh, cosh and tanh– basically the opposite of sin/cos/ tan.
For a much better definition take a look at.Just a bit further MeasurementsEXP– Allows you to enter exponential values easily. Say you wanted to enter 200000000 on your calculator, rather than pressing 2 with 8 zeros after it, all you need to press is EXP then the number of digits you want (8). Makes more sense with massive numbers.RAD, GRAD and DEG change the mode of the computer to accommodate for different measurement of angles- Radians, Degrees and Gradian (Grads)RAND- Rand will generate a random number between 0-1. If you want more options with numbers between a specific point use 10.rand.ENG = Engineering Units– Change the number in the display to engineering notation instead of decimalAnd there you go I think the most common buttons on a calculator.
