Le forum de XCAS

idea, to select a part of the expression in the output, the menu [m] shows only some options of symbolic manipulation, I think there should be a new menu called [catalog] to access the a number of commands. It is important in the learning of algebra as an option of direct manipulation, without returning the expression to a new line and manipulating it by the name of command functions.

input
laplace(2*t*e^(-3*t)+5,t,s)

output

(5*s^2+32*s+45)/(s^3+6*s^2+9*s) |
ctrl+a

(5*s^2+32*s+45)/(s^3+6*s^2+9*s)

[m] [catalog] partfrac
output
5/s + 2/(s+3)^2

You already have access to all commands of the Xcas menus.

In the output line, when calling [?] Does not execute any action, with the menu [m] on output line, I can only operate with the commands that the list shows, the idea is to execute several commands on the expression de output line
