I want the pasted text to include the enter key press.

In my next version I want to include scripting. That will allow you to use multiple commands with one hotkey! But for the moment you could also do this with a macro or the remap function. It is a bit more complicated but will work.

I'm trying to get the following behaviour to happen: Paste my email address "a@b.com" into the control that currently has the focus and Hit tab to advance to the password box.

Use [SHIFTD][2][SHIFTU] that is if your keyboard has the @ sign with the 2 key on the keyboard. If not see which key it represents and use shift plus that key. So just simulate pressing down the shift and then the key with the @ on it and release the shift. This is how it should look: [u][s][e][r][n][a][m][e][ShiftD][2][ShiftU][d][o][m][a][i][n][Period][c][o][m][TAB]

For UK keyboard the @-sign is on the apostrophe key so then it will look like this: [u][s][e][r][n][a][m][e][SHIFTD][APOSTROPHE][SHIFTU][d][o][m][a][i][n][PERIOD][c][o][m][TAB]
