The simplest ws to move your insertion point to the beginning and end of a text line is just to click there. To move your insertion point to the beginning of a document, press ctrl+home, and to move it to the end of a document, press ctrl+end on your keyboard.
If you press home, the line showing where your text will go goes to the beginning of the line. I don't know if anything makes it go to the beginning of a sentence, and if you're trying to make the mouse go there, I don't know that either.
Start entering text at the start of the line. After you have entered the text, press delete until the line retracts and disappears. If you want your text underlined, highlight your text and use the underline feature of your word processor.
If you press it while in the middle of text on one line, it will move the rest of the text onto the next line, so there will be no gap between them. So Enter will move text down one line. However, with paragraph formatting applying, a full blank line will appear between the text. So to put text on the immediate next line, you would now use Shift-Enter.
Press the Enter key two times.
If you are referring to a line of text in say, a Word document, the "Home" key (usually located near the page up/page down keys) will get you back to the start of the line on the left hand side of the page.
The Home key will bring the cursor to the beginning of a line of text.
Enter key or Return on Mac.

There are several ways of doing so. You can drag across it. You can click at the start of the line. You can put the cursor at the start of the line and then press Shift - End.
