    <p><strong>short summary:</strong></p> <p>I am trying to create a program that will send keyboard events to the computer that for all purposes the simulated events should be treated as actual keystrokes on the keyboard.</p> <p><strong>original post:</strong></p> <p>I am looking for a way to generate keyboard events using python.</p> <p>Assume that the function receives a key that it must simulate pressing, like so:</p> <pre><code>keyboardevent('a') #lower case 'a' keyboardevent('B') #upper case 'B' keyboardevent('-&gt;') # right arrow key def keyboardevent(key): #code that simulated 'key' being pressed on keyboard </code></pre> <p>The above are obviously examples, but what I am looking for is a library, module, or whatever, which I can use to simulate keyboard events.</p> <p><em>note</em>: This is different than sending characters to notepads, or inputting text into fields or such. I want the python script to simulate an actual keyboard event, the computer will think that there is really a keyboard event.</p> <p>Extra Note:</p> <p>I don't want to send keystrokes to the active window - I want the system to believe the keyboard's keys are being pressed, subtle difference, as some active-windows do not accept certain key-combinations, or if I wanted to use keyboard shortcuts for background processes through my script, they don't need to go through the active-window</p> <p>So far I have looked at these things:</p> <p><a href="https://stackoverflow.com/questions/9318690/generate-keyboard-events-for-the-frontmost-application">Generate keyboard events for the frontmost application</a></p> <p><a href="https://stackoverflow.com/questions/6868167/how-to-generate-keyboard-keypress-events-through-python">How to generate keyboard keypress events through Python?</a></p> <p>Which were all about apple and didn't help at all.</p> <p>And this:</p> <p><a href="https://stackoverflow.com/questions/2791839/which-is-the-easiest-way-to-simulate-keyboard-and-mouse-on-python">Which is the easiest way to simulate keyboard and mouse on Python?</a> </p> <p>Which seems like it might be what I need, but I can not find the library for it or any documentation.</p> <p>I have searched more places as well, but have yet to find a solution.</p>

    1. COThe only thing I know of is [SendKeys](http://pypi.python.org/pypi/SendKeys), which is Windows only. This seems like a problem that will not have a cross-platform solution. Why do you need this? What problem are you solving?

    2. COFor `X` platforms there is `xdotool` but is usually not installed by default. I believe reading the docs for `X` it should not be hard to write a minimal module in C that does what you want(I believe there was a `xsendkeys` program around some time ago).

    3. CO@StevenRumbalski thank you, this looks promising, but i would like to add, i will edit my question. i dont want to send keystrokes to the active window - i want system to believe the keyboard keys are being pressed, subtle difference, as some active-windows do not accept certain key-combinations, or if i wanted to use keyboard shortcuts for background processes through my script, they dont need to go through the active-window.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
