There are some javascript tricks able to enable the hidden design mode.
To do that you just need to put this: “javascript:document.body.contentEditable%20=%20′true’;%20document.designMode=’on’;%20void%200″ in your address bar and you can switch it off with “javascript:document.body.contentEditable%20=%20′false’;%20document.designMode=’off’;%20void%200″

The latest command doesn’t work in Firefox3.
These commands should instead should work in Firefox3 too:
“javascript:document.body.contentEditable=”true”;void0″ and “javascript:document.body.contentEditable=”false”;void0″

If you are coping a file (uploading/downloading) with ssh and the connection is interrupted. Then if you need to continue to downloading/uploading the latest processed file, then you can define scpresume:
alias scpresume=”rsync –partial –progress –rsh=ssh”
and then you can use it with the same syntax used by scp.
