How to send ctrl+D into Emacs' Eshell? It looks like Emacs intercepts all my attempts to send any control key + a letter to shell and tries to interpret it as it's own command. How to send that combination to Emacs' EShell?
For the specific case of C-d, you can use C-c C-d, which is bound to eshell-send-eof-to-process. Otherwise, use C-q for quoted-insert, to force the following character to be inserted into the buffer even if it has a key binding in Emacs.

I need the command that can open a file without closing emacs
I have tried C-X C-F
You were on the right track, but it's C-x C-f rather than the capitalized form C-X C-F which would imply the Shift key is held in addition to Control. So to be explicit, you want to hold Control down while pressing x and f in succession.
The C-x C-f sequence will invoke the find-file command under vanilla emacs, which lets you choose a file to open in a new buffer.
See also Emacs Manual Section 18.2 Visiting Files.
Emacs distinguishes between uppercase and lowercase letters.
Emacs doesn't pay attention to the actual pressing of the shift key but it pays attention to the receipt of the key combination, so if you press C-F it doesn't matter whether you physically pressed ctrl+shift+f or caps-lock followed by ctrl+f.
The exact combination is C-x C-f, without shift or caps-lock.
The right way is to hold your 'Ctrl' key and press 'x' followed by 'f', Make sure your capslock is off. and be in editing mode.
I desire to review all the key-sequences with prefix "C-c"
Issue C-c, it prompts
and remind that C-h C-n to reference the next page.
I want to view them all simultaneously within a single buffer and tried to C-x 1 with intention of see them in a full-screen buffer.
Unfortunately, such an operation is deactivated in the mini-buffer which C-c invoke, In contrast, grep-find, grep's minibuffer could be manipulated with C-x 1.
How could view all the commands prefix with C-c
You should be able to use C-c? to see all the commands prefixed by C-c. If, by chance, C-c ? is bound already, try C-cC-h
When I'm running a terminal inside emacs (with M-x term) I can't seem to use commands that start with C-X, such as, say C-x o to switch panes or C-x C-c to exit. Instead it seems that the terminal itself is receiving these C-x signals. By contrast, C-c commands are received by emacs itself. How can I change this behavior?
term has two different input submodes. In the default (character) mode, C-x simply transmits a literal control x to the terminal. Many keybindings which are normally available in the C-x map are instead now in the C-c map, so you can switch to a different buffer in the other window with C-c 4 b. Or you can switch to line mode with C-c C-j (and back to character mode with C-c C-k).

Currently, if I press C-h c, then trice press ESC key on keyboard I get result
ESC ESC ESC (translated from <escape> <escape> <escape>) runs the command keyboard-escape-quit
What the difference between ESC and <escape> and how can I use this difference to make more keybindings?
Found solution in emacs mailing list archive:
The escape key usually is linked to the escape char, but the two
are different. Under a tty, Emacs receives the exact same byte-sequence
from the terminal if you type the escape key or if you type C-[ (both
send the escape char).
Under a GUI, on the other hand, Emacs can distinguish the two, so under
a GUI, the escape key doesn't send ?\e (aka ESC for kbd) but escape
(aka <escape> for kbd) which is usually turned into a ?\e via
function-key-map (i.e. only if there's no corresponding binding for the
key sequence with escape).
Same thing happens with tab (i.e. TAB (aka C-i) vs tab) and return
(i.e. RET (aka C-m) vs return).
In finding string in the current buffer, I know that we can use C-s or C-r, then you'll have the minibuffer prompt of what the string to be search. I know that we can use M-p or M-n to go to that prompt, but unfortunately emacs will display the previous search query.
I don't like using backspace to delete it, is there any key in which the prompt can be cleared from previous searches?
Thanks
Are you saying you want to change your search term while you are already in the process of searching?
A couple of simple options are:
Break out of the search first. I usually just do something which moves point, such as C-a. Then when you C-s again, the prompt will be blank (unless you type it twice, in which case it will search for the previous pattern again).
RET is isearch-exit, but that has a different effect with no pattern, and I prefer the consistency. You could also use C-g (isearch-abort), but you may need to type that repeatedly, depending on what happened up to that point.
ESCESCESC runs isearch-cancel which will reliably "Terminate the search and go back to the starting point", which may sometimes be preferable to C-a which will leave you on the line where you typed it.
You can edit the pattern on the fly with M-e, and then delete the whole thing with normal editing commands. After editing, type RET to continue searching for your newly-edited pattern.
Type C-sC-hC-h for the built-in help.
Try binding a key to the M-x search-forward command.
(global-set-key (kbd "C-s") 'search-forward)
This will automatically focus on the minibuffer and clear previous input.
