hotkey | Trigger an action on an element with a keyboard shortcut | Keyboard library

I'm analysing a package that's quite big and as I'm going down, I've selected a few lines that I deem important, every time I click on the line number, PL/SQL Developer marks the line with a blue number starting from zero as the image show. I know there's a hotkey to jump between them so that I don't have to drag the wheelbar and find them on my own. Does anyone know how to do that?

Example

I'm using the following XMonad.Layout.ThreeColumns layout

Per the instructions at https://stackoverflow.com/a/11378213/892770, I've registered a global hotkey for my WPF app like this:

My program is waiting for the F4 hotkey to be pressed in order to exit.

I am calling Sleep(1) because without this, I am using 18% of my CPU. Is this the correct way to do this? My gut is telling me there is a better way.

I know that keyboard inputs are interrupt-based, but is there any way to make a thread sleep until a keyboard state change is registered?

This code works on Windows 10 but not on Linux. Linux does not seem to receive any keyboard events at all. When interrupting the program on Linux with Ctrl-C, this is the stack trace:

I'm currently making a very basic script that takes a screenshot of the computer every 10 minutes. However, I've now been asked to also add in the option to click a hotkey to activate it manually.

I found this, which essentially helps me some of the way:

I want to right click on a node to zoom into that node, then right click again to completely reset the zoom and pan to its starting state. Furthermore, I may in future wish to hide the viewer's built-in toolbar and perform the zoom-out with a hotkey. So "just press the existing Home button" is not a solution for my use case.

I already have the zoom-in working using ShowBBox().

I cannot find a way to programmatically zoom out exactly like the Home button would do.

• The viewer has no ResetZoom(), HomeButtonPressed(), or any such method that I can find.
• Setting .ZoomF back to 1.0 is not sufficient because it does not simultaneous center the panning (and Pan(0,0) does not center the pan either.)
• gvMain.ShowBBox(gvMain.Graph.BoundingBox) does not work (the zoom changes very slightly, but not to a fully reset state akin to the Home button.)

I am using vim on a browser-based RDP session. Unfortunately, my browser is realllllly particular about capturing the "ctrl-w" key combo, because of unrelated-to-my-specific-use-case security reasons. This prevents me from using the pane feature of vim, because when I try to switch panes, my tab closes (!!!). Is there a way to change the "pane switch" hotkey to something besides "ctrl-w" in vim?

I have implemented MenuFlyoutItem.KeyboardAccelerators and below you can see the code
