.screenrc

Updated my .screenrc a bit ( looks like this ):

hardstatus alwayslastline “%{=}%{g}[ %{W}%H %{g}][%= %{w}%?%-Lw%?%{r}(%{W}%n*%f %t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][ %{B}%Y-%m-%d %{W}%c:%s %{g}]“

Firefox: good to know

If Firefox fails to start with this error message “Firefox is already running but is not responding” do this to fix it:

First check in your process list to see if firefox is already running and if it is, kill it ( the mozilla page rekommends that you reboot your computer but who wants to do that ).

If you can’t find any firefox process or you still get this message after you killed it, go into your profile folder ( ~/.mozilla/firefox/XXXX/ ) and remove ‘.parentlock’.

Now Firefox should be able to start successfully.

Vim tips

If you want to search for something you select in visual mode: 1) yank 2) / 3) CTRL-R” 4) That is: y/^R” (note: ” is the default yank buffer. You could use a named buffer as well if you want.)

~ — switch case of character under cursor

i_CTRL-A — In insert mode, insert the previously inserted text.

{visual}g? — Rot13 encode highlighted text g?? — Rot13 encode the current line

CTRL-A — Add [count] to the number at or after the cursor CTRL-X — Subtract [count] from the number at or after the cursor

J - join the current line with the line below it.

. — repeat the last change

If you want to change a quotation: “This is a quotation” And want to change it to: “blablabla” Start on the first letter of the quotation and press ct” (Change Till “)

ga - with your cursor over a character, it will show you the decimal, hex, and octal codes of the character. Great for non printable characters.

To insert special characters, you’ll be interested in digraphs. :digraphs will show you a complete table of special characters, plus their two character code, plus their ascii number. You can insert digraphs using ctrl-k plus the two character code. For example ctrl-k SX results in ^B being inserted
