Answer A: Reset all buffer variables to default in Emacs
`M-x kill-local-variable` `RET` `c-basic-offset` seems to work, but only temporarily. If I save, and close Emacs, and revisit the file, the changes do not persist. I that in an affected directory, each file must be visited and a permanent version of this must be performed. Not ideal.

Question How to view history of tabs sent to devices in Firefox
I will often send tabs to other devices for later viewing and sometimes these tabs get lost between power-ons or swiped away if I don't open them immediately. Is there a place where I can view the history of sent tabs and the path they traveled?

Comment Post #287926 `TAB` = `C-i` is okay with me. I think still some text is missing in the mode question. If I get your point, either mode works. It would be convenient to `TAB` while in insert mode to correct, but I won't let this restrict the solution.

Comment Post #287926 Great point. Ideally yes I'd like it to be extensible. > You mention but not the mode (normal or insert)? Note that = so if you map one you map the other. > > See also :h i_C-t. I'm not understanding this part. I think some text got cut out.

Comment Post #287709 This is outstanding, thank you! Plus, if I figure out the cause of the black bar, the command becomes very clean and simple. I am withholding marking this as the solution in the case that a grafx2 one comes along.

Comment Post #287703 I was considering this, but reasoned that it would be hard to portray the difference, besides the first taking up a lot more of the page, particularly with a white background. Is the intended goal not clear without a picture?

Question How to make background transparent and trim to content
Question Is there a way in `grafx2` to make the background transparent and trim to content? This could be done during save. My process now when making images for documents is: 1. Make image in `grafx2`. 2. Open image in `gimp`. 3. Add alpha layer. 4. Select background by color. 5. Clear (...

Comment Post #287367 This is a very enlightening post. Please let me know if the following questions belong in their own post. 1\. Is there a way to view a list of all available `ex` commands like `delete`, `put`, etc.? 2\. I am used to registers being represented with `"`. Why is it `!` in this context and how did...

Answer A: How to redraw screen putting specific line at top without moving cursor
The best I've come up with since, when the line in question is often returned to, is to go mark the line you want up top with `mz` and the line you are working on with `mw`. Returning your workspace to order then becomes: `'z` `zt` `'w`.
