Re: lynx-dev [dev.4] arrow key patch (was: Re: Lynx 2.8.3dev.4 and arr

[yury . burkatovsky]

Dear lyncei,

I applied this patch to my lynx2-8-3dev.4 built on an HP-UX 10.20 box with 
slang 1.3.8.

Unfortunately, that did not help.

I could not notice any pattern when my lynx established a decent arrow key 
mapping and when it refused to do so until I paid attention at the xterm 
options in use.

The xterm window on my workstation tends to set up spuriously "Enable 
Application Cursor Keys" and "Enable Application Keypad" booleans, without a 
visible cause. So, when pine (or any other xterm-based application) suddenly 
starts a wrong behaviour, I immediately check these options and reset them 
using a pop-up "VT Options" menu. After that all the things resume to work 
properly.

I found in this thread that these same options could impact on the arrow 
mappings, and that was it.

Whenever the options are set, I get a wrong behaviour no matter if your patch 
is applied or not; when they are disabled, all arrows work properly.

BTW, lynx built with ncurses-5.0-990626 did not support the mouse on my box, 
while lynx with slang does. It was not the lynx's blame, because ncurses test 
utilities also are not sensitive to mouse clicks.

Heh.  I can understand the confusion ...

Let me make it a real patch, which should (hopefully) solve the problem
that you and others are having.  If this *doesn't* work for you, please
let us know.
