AHK keystroke to show image only while it's pressed

Question

Good day,

I'm trying to create a script for AutoHotKey (AHK) which will show an image when having pressed Caps lock+A simultaneously and will hide after releasing the keys.

My current solution shows the image, but it only will go away after pressing Esc:

#Persistent
SetCapsLockState, AlwaysOff
#If, GetKeyState("CapsLock", "P")

a::
Gui +LastFound +AlwaysOnTop +ToolWindow -Theme -Border -Caption
Gui, Color, FFFFFF
WinSet, Transcolor, FFFFFF
Gui, Add, Picture, x0 y0 w1827 h635, C:\Users\User\Image.png
Gui, Show, xCenter y360 w1827 h635
Gui, Margin, 0,0
return
GuiEscape: 
Gui, Cancel
Gui, Hide
return

I've experimented with setting a state or a UP:: but nothing worked. Looking forward to some help.

Answer 1

KeyWait seems to be what you are looking for.

From the docs:

KeyWait

Waits for a key or mouse/joystick button to be released or pressed down.

KeyWait, KeyName , Options

So in order to delay the script until the a key to be released, you would implement it as so:

KeyWait a

Final Code:

SetCapsLockState, AlwaysOff
#If, GetKeyState("CapsLock", "P")

a::
Gui +LastFound +AlwaysOnTop +ToolWindow -Theme -Border -Caption
Gui, Color, FFFFFF
WinSet, Transcolor, FFFFFF
Gui, Add, Picture, x0 y0 w1827 h635, C:\Users\User\Image.png
Gui, Show, xCenter y360 w1827 h635
Gui, Margin, 0,0
KeyWait a
gosub GuiEscape
return

GuiEscape: 
Gui, Cancel
Gui, Hide
return
