Hi All,

>From https://www.kernel.org/doc/html/v4.10/process/email-clients.html, I
understood that, my current email client ( that is gmail web ) is not good
for submitting patches. So I was tying to setup a mail client which is
compatible with `git send-mail`. But I was not able to get a satisfactory
result in that.

For now, I followed the instruction of Johannes Schindelin and submitted a
pull request . Please see https://github.com/gitgitgadget/git/pull/376

I agree with this, But that may require some more profficiency in TCL/TK
programming which I don't have. This is the first time I am looking into a
TCL/TK source code.
Any way I will try to integrate the gui gradually in feature. But
unfortunatly, I may not be able to do that now.

IMHO, Using a uniform shortcut-key code/foramat for both application can be
considered as nice feature.
But, whether we should share common shortcut-scheme with both application is
a different question.
Currently, both apps don't have a common shortcut-scheme. So in this
situation, only sharing custom-tool's shortcut-scheme with both applications
doesn't look like a good  idea to me

I agree with you. It is an important point. After reading this, I checked
current status of these issues. What I found is given below.

1. When user provides an invalid sequence for the shortcut, it will cuase the
entire gitgui application to crash at the startup

2. When user tries to overwrite existing shortcut, it will not have any
effect. Because, built in shortcuts will overwrite user provided one. But
still, wrong menu accelerator label will persist for custom tools

Since #1 is a serious issue, I tried to find out the function which does the
keycode validation, but I haven't succeded till now. ( I found the C function
name  which is "TkStringToKeysym" from TK source, but I couldn't find its TCL
binding ). It will be helpful if any one can help me on this.
