I'm trying to use htop
in tty1. However, some of the function keys don't appear to work as normal. F1 and F2 do nothing, and F3 seems to trigger setup (which should normally be triggered by F2). In addition, F4 and F5 don't work. Also, when I try and press Esc to get out of these screens, I have to press it twice.
In a normal terminal (terminator
), the function keys work fine. However, I have to press Esc twice here too, so perhaps that's a red herring.
How can I use these function keys in tty1?
EDIT
In tty1, if I press Ctrl+v then F1 to F5, etc. I get the the following output:
^[[[A
^[[[B
^[[[C
^[[[D
^[[[E
In terminator
, I get
^[OP
^[OQ
^[OR
^[OS
^[[15~
The function keys above this are equivalent (e.g. ^[[17~
for F6).
EDIT 2
In response to Stéphane Chazelas's comment.
$TERM
is the same in tty1 as in my "normal", working terminal. It isxterm-256color
.- I am not using screen or tmux.
- I am using
htop
1.0.3, although my first edit seems to point to it being an issue upstream ofhtop
.
"Does
infocmp -L1 | grep key_f

I'm not sure what you mean by "match what those keys send for you", but I ran this command in both my normal terminal and tty1, and the output was identical, as below.
