Ignoring certain characters in linux

[cancub]

Sup, HP? Using Ubuntu 16.04 I've noticed a small bug when I set up a host removal hotkey like so:

k.type(VK_BACK_SPACE);
k.type(VK_BACK_SPACE);
k.type(VK_BACK_SPACE);
k.type("ssh-keygen -f \"/home/<user>/.ssh/known_hosts\" -R <ip>"); 

For some reason, the "w" in "known" is dropped. Result from the call to the activation key combo of Q+W+NumPad-1:

ssh-keygen -f "/home/<user>/.ssh/knon_hosts" -R <ip>

However, adding a second "w" (i.e., "knowwn") makes everything fine.

ssh-keygen -f "/home/<user>/.ssh/known_hosts" -R <ip>

Edit: It's happening with each command I add. For example, I need two "d"s in

tcpddump -i vtnet3 -e ether proto 0x8100

It seems like this has to do with the keys used for the combo as they appear to be the letters that are being removed from the output. Using "Y+H+K" results in

ss-egen -f "/home/<user>/.ssh/known_hosts" -R <ip>
