Execute from cursor to beginning of code block in RStudio - r

Say the cursor is placed just after (cyl)in RStudio (as in top screenshot). Is there a way to run from the beginning of the code block to the cursor (as in bottom screenshot)?

Try Ctrl+Alt+B
This runs your code from document beginning to current cursor line.
Source: RStudio

My workflow in this situation:
Shift (keep holding)
push Arrow up (release button)
push Pos1
Release all
Ctrl + Enter

Atom editor end of line shortcut (without end button)

In my laptop keyboard I can move cursor to end of line by pressing FN + right arrow buttons.
Now I am coding on a desktop and this keyboard doesn't have that combination.
I can move cursor to end of line by pressing "END" button but I don't want to use END button I just want to add this functionality to a similar combination what I had in my other keyboard.
So I am looking a way to create shotcut to press ALT + Right Arrow to make same functionality as END button. Is there any way to do that ?
Thanks.
After reading all documentation and making some tries I found out how to move cursor end of the line.
First go to File -> Keymap this will open keymap.cson file on here just add codes under 'atom-text-editor'. It will look like as below.
'atom-text-editor':
'alt-right': 'editor:move-to-end-of-line'
'alt-left': 'editor:move-to-beginning-of-line'
So now you can move your cursor end of line by pressing ALT + Right or visa versa.

QWebEngineView interprets AltGr press as left arrow in WSL2

Context:
Custom Qt application embedding a QWebEngineView widget used to display an Auth0 page.
Compiled for Fedora against Qt5.15.2, run on Windows in a WSL2 distribution. vcxsrv is used to display the X11 window.
Symptoms:
In the email text field, when I try to type # using the AltGr+à key combination (french keyboard), the cursor jumps 1 character left as soon as I press the AltGr key. Oddly, the # character is properly added. For instance, if I try to type test#, the result is tes#t and the cursor is right after the #.
Each time I press AltGr alone, the cursor jumps left.
In a QLineEdit, no issue typing #
Tests done:
chromium-browser launched in the same WSL2 distribution: works as expected (QtWebEngineView is based on chromium)
Played with the locale settings but no success
Played with the QTWEBENGINE_CHROMIUM_FLAGS env var but no success (list of Chromium flags)
Quite similar issue:

Any help to understand what is the culprit would be greatly appreciated!

PyCharm R plugin: how to clear the console?

I am running an R file with the PyCharm R plugin. Is there a way to clear the console? I have tried ctrl + L and cmd + L, but neither of them works.
I can't find a default key-binding for clearing the R-console in PyCharm, but you can press Ctrl-Shift-A (or navigate to Help-> Find action) to find the action, and set your own binding, in this case you would want to search for/bind clear all (not clear).
Put the mouse cursor on the area of the R-console where the text is that you want to clear.
Press the right mouse button. Choose the option "Clear All".
See screenshot.
