Are there shortcuts for text editors/processors to delete the rest of a line?

The cursor may stay in the middle of the line and there may be necessity to delete whatever stands from the right side of the cursor, but only till the end of current line. I don't know how this called properly and if there is such function in text editors, but if there is such, what shortcut usually used for this? I'm mostly interested in Notepad++.

Delete to end of line

In Notepad++ it is the following shortcut:

CtrlShiftDelete Delete to end of line

"Delete to end of line"

Windows, try this:
Hold SHIFT and hit End (selects the text) then Delete.

Linux, some editors mimick (i.e. 'works' the same as) windows editors, "native editors" (especially those running in shell/terminal) e.g. nano (pico) usually differ:
First press ENTER to split the line, creating a new line with the end part of the previous, then hold CTRL and hit k to kill the line.
