There are limits to the number of characters that the different Remarks fields will accept during listing Add/Edit:
Public Remarks= 1500 characters
Confidential Agent Only Remarks= 500 characters
Public Remarks (Addendum)= 2400 characters
These numbers include punctuation, spaces and carriage returns (hitting the Return/Enter key on the keyboard). Hitting the Enter key actually takes up 2 characters.
As you enter text in the field, Matrix keeps a running count and will let you know how many characters you have left:
There have been instances where users have hit the Enter key several times in a row, leaving a large blank space between paragraphs. Because the field is not very tall, it is possible that there is text that is hidden further down than the bottom of the field- something to keep in mind if the number of characters remaining does not align with the amount of text you see on the screen.
