IntelliJ IDEA Cmd+Shift+A (Find Action) causes error log: "Nothing appropriate" in a yellow terminal titled "apropos"

Original close reason(s) were not resolved
When I go to use the keyboard shortcut for "Find action" (command+shift+A), macOS opens the terminal and with some output: myPreviousSearchResult\;type\=a,(replace myPreviousSearchResult with the previous search result you did on in the search bar).
It doesn't happen all the time, which adds to the peculiarity, and often does not happen when I first launch the search bar. Only the second search and onwards.
Here is an example:
Answering my own question because finding the notice took me too long and was quite frustrating. I considered glitchy IDE plugins, other apps installed, and searched the web for all sorts of terms. I didn't consider the OS was adding shortcuts for random things like this.
You need to disable a keyboard shortcut in System Preferences > Keyboards > Shortcuts > Services > Text (dropdown menu) > Search man Page Index in Terminal.
If anyone has suggestions on debugging keyboard shortcuts (finding out which apps are handling them), please let me know.

Showing and hiding multiple windows in PyQt5
(1 answer)
Closed 2 years ago.
I'm trying to create a simple app which consist of two windows. The first one is a Login Page and the second is a Registration page. The dynamics are as follows:
The first window is the Login window with two buttons; Login Button and Register Button.
If the login button is clicked, it starts a session if the credentials are correct.
Clicking the second button should close this window and open a new registration window.
The registration window has two buttons as well, the first simply confirm the registration, the second is to cancel the registration.
This cancel button is supposed to close the current window and open the Login window.
Steps 1 through 4 work perfectly, but in step 5 it keeps does not close the current window and simply opens a new Login windows.
Please write a basic code as an example of how to close the window using PyQT5. I don't want you to write all code but just a generic one. I just want to have an idea how it works and use it in my own code.
One way to approach this problem will be to implement a separate controller class. This class will control all the windows you want to show or hide.

How to simulate string keyboard input using Python?
(1 answer)
Closed 5 years ago.
I want to send a keyboard keystroke to active window, for example key A or Backspace using python. How can I do this?
I know active window coordinates as well (if it can help).
The Windows API method to do this is SendInput which is part of the User32 library. It sends keyboard and mouse input to the foreground/active window. SendInput uses the INPUT structure, specifically called KEYBDINPUT. It has the option of sending more than one INPUT because the first parameter details that:
nInputs [in]
Type: UINT
The number of structures in the pInputs array.
An example of using SendInput in Python is specified in the answer on this question.
You use the MapVirtualKey function to map a virtual key code to a scan code

chrome extension: how to bind/hook to the browser's "search invoked" event?
(1 answer)
Closed 5 years ago.
Is there a way to access the find box from a chrome extension? I want to manipulate the text in the find box when the user hits ctrl+f
There is no way to directly access the Find Dialog when it is called/invoked. These are based on the solutions on the related question - Chrome Extension: How can I show the find bar and supply text for it? and chrome extension: how to bind/hook to the browser's “search invoked” event?
However, the workaround for this is use the Command API or window.find().
Command API
You can try chrome.commands, use the commands API to add keyboard shortcuts that trigger actions in your extension, for example, an action to open the browser action or send a command to the extension.
Hope this helps.

How do I create text box with watermark effect in windows phone?
I have two text boxes
Username
Password
Now I want that in first text box, Username by default written in light weight and If I write in that text box, it should be disappear. How to solve it?
You need to use PhoneTextBox from windows phone toolkit for this.
You can download it from here.
You can also directly add it to your project by typing the following into your package manager console :
PM> Install-Package WPtoolkit
Now, add a reference of toolkit inside "phone:PhoneApplicationPage" tag in the xaml page as follows:
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
Finally, use PhoneTextBox control.
<toolkit:PhoneTextBox Hint="Username"/>
