Thank you very much!

Yes, the manual states that Textadept uses $LANG to determine language, or a *~/.textadept/locale.conf* file.

That is strange indeed. If you move your locale file from Textadept's home directory to your *~/.textadept/locale.conf* (note the simpler filename), do you still see the same problem? I cannot see why changing your $LANG from "zh_CN.UTF8" to "wp_CN.UTF8" would affect being able to change focus to the Find & Replace pane.

Textadept is not smart enough to go searching for fonts that can display all characters. It relies on you to specify better fonts, as you have done in your attached *init.lua* file.

I would probably connect to the `events.CHAR_ADDED` event and look for a character that comes after one of your markers. For example:
if ch ~= string.byte(':') then return end
if buffer:get_cur_line():match('TODO:$') or
-- Perform highlighting of TODO or FIXME just added.
When you type ':', the event handler looks for a preceding "TODO" or "FIXME" and proceeds to highlight it.

The file browser module does not persist between sessions. I'm pretty sure it can be extended to do so, but I'll leave it to someone else.
> I'll also share my init.lua in attached files. I'm looking for an option that will fold all fold-points or blocks that are longer than 100 lines.
I suppose you could:
1. Iterate over all buffer lines via `for i = 0, #buffer.line_count do ... end`.
2. For each line, `i`, check the fold level via `buffer.fold_level[i]`.
3. If it's a fold header (`level & buffer.FOLDLEVELHEADERFLAG > 0`), note the line and its level minus the header bit, and start counting from 0.
4. When you find 100 subsequent lines whose fold levels are greater than the noted level in step 3, you can fold the line noted in step 3.
5. Continue looking for header lines after the last folded line.
Note that you will have to handle blank lines `buffer.FOLDLEVELWHITEFLAG`. You will also have to correctly determine the index of the last folded line for step 5 (perhaps `buffer:get_last_child()` may be of help).
I hope this helps.
