Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.1 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

As I was not able to find any documentation for the Linux VT (called tty) I choose to reference the VT100/220 documentation and I consider the following behavior a bug. - The home key (above your cursor keys or fn-left on a MacBook) sends the sequence: CSI 1 ~ which corresponds to some non-existent key labeled "Find" - The end key (fn-right on a MacBook) sends the sequence CSI 4 ~ which corresponds to some other non-existent key labeled "Select" These keys may have existed on the same position on the keyboard as our modern Home and End keys but according to the documentation they are not Home and End: http://vt100.net/docs/vt220-rm/table3-1.html The usual escape sequences for the Mac / PC Home and End keys are: CSI h for home and CSI F for end. Both the Gnome Terminal and the original XTerm do send these escape sequences. The easiest way to get out of the Terminal mess is probably a standard to be defined by the few implementors of Virtual Terminals left. But as long as an implementation doesn't document its capabilities and control mechanisms every behavior can be considered a bug. There are other key mapping related issues, too. Like meta on an alt key when Meta keys are there ...
