[Solved] Program a Keypress

[Handoko]

The page down key on my keyboard doesn't work. I thought it was some mechanical issue so I opened the keyboard. No, the mechanical part was working correctly and nothing I can repair.

I am thinking to write a small utility to simulate page down keypress using shortcut, maybe [shift]+[ctrl]+[d].

I know how to do trayicon but please tell me how to simulate page down keypress using code. I use Linux.

you do know about http://wiki.lazarus.freepascal.org/MouseAndKeyInput right?

In theory you can use the package lazmouseandkeyinput.lpk, found at
.../lazarus/components/mouseandkeyinput/

However I could not get the package to compile (using FPC 3.0.2 Lazarus 1.8.0RC2) on a recent 64-bit Linux.
I get a linking error about ld being unable to find -lXtst

I know I used it successfully some time ago, probably Laz 1.6.0 or around that version.
There is an example of simulating both key and mouse input via code in the /example/ subdirectory if you have an older Lazarus setup where it compiles OK.

Me too cannot compile using Lazarus 1.6.4 on Linux 64-bit. It only said "Error: Error while linking".

I'm guessing you guys already know or have installed the xorg devel packages but just in case (and I quote)

Xtst is provided by xorg and on most Linux distros header files (or development libraries) are provided by devel packages, so you need to install xorg devel packages.

and in this case I guess you need to have both the 64bit and 32bit devel packages installed based on the target of your compilation not the bitness of your IDE (again sorry for being captain obvious).

Thank you for the info.

I found that we do not have to instal the xorg-dev package (because it will include a lof of other packages that I don't need), I only install libxtst-dev to make the lazmouseandkeyboardinput.lpk and its example to work correctly on my Ubuntu 16.10 64-bit.
